IIterating through hotbar and inventory

I created this predicate which checks number of items in a stack, I've then duplicated this predicate into a seperate file for the different ranges I am checking.I am using this predicate to trigger a custom model change.
    "condition": "minecraft:entity_properties",
    "entity": "this",
    "predicate": {
        "type": "minecraft:player",
        "slots": {
            "hotbar.8": {
                "items": "minecraft:cooked_chicken",
                "count": {
                    "min": 1,
                    "max": 7
                }
            }
        }
    }
}```

Is there a way to  iterate through each hotbar slot and inventory slot without having to create an individual predicate for each one, as I am checking multiple custom_data_models all based off of cooked_chicken. If I try inventory.* or hotbar.* it triggers if there are items in any slot, not just the one I am checking. 

Here is the main function that is being checked each tick
```execute if predicate itemscaler:hfc_one_seven_lv0 run item modify entity @s hotbar.0 itemscaler:set_hfc_0
execute if predicate itemscaler:hfc_one_seven_lv1 run item modify entity @s hotbar.1 itemscaler:set_hfc_0
execute if predicate itemscaler:hfc_one_seven_lv2 run item modify entity @s hotbar.2 itemscaler:set_hfc_0
execute if predicate itemscaler:hfc_one_seven_lv3 run item modify entity @s hotbar.3 itemscaler:set_hfc_0
execute if predicate itemscaler:hfc_one_seven_lv4 run item modify entity @s hotbar.4 itemscaler:set_hfc_0
execute if predicate itemscaler:hfc_one_seven_lv5 run item modify entity @s hotbar.5 itemscaler:set_hfc_0
execute if predicate itemscaler:hfc_one_seven_lv6 run item modify entity @s hotbar.6 itemscaler:set_hfc_0
execute if predicate itemscaler:hfc_one_seven_lv7 run item modify entity @s hotbar.7 itemscaler:set_hfc_0
execute if predicate itemscaler:hfc_one_seven_lv8 run item modify entity @s hotbar.8 itemscaler:set_hfc_0

execute if predicate itemscaler:hfc_eight_fifteen_lv0 run item modify entity @s hotbar.0 itemscaler:set_hfc_1
execute if predicate itemscaler:hfc_eight_fifteen_lv1 run item modify entity @s hotbar.1 itemscaler:set_hfc_1


tellraw @s "I am running"```


Etc, for each usecase that needed to be checked (if my math worked out correct worked out to a few thousand checks per player)

Here is a few examples of the the Item modifiers responsible for updating the model.

```[
  {
    "function": "minecraft:set_custom_model_data",
    "value": 2500
  }
]```

```[
  {
    "function": "minecraft:set_custom_model_data",
    "value": 2501
  }
]```

Finally, because it is updating the model, I run into two additional problems, one is that one the model updates, it changes its custom model data number, and will no longer stack, I also have to check each individual varient of cooked chicken seperately if I don't want it to affect minecrafts regular cooked chicken.

The method I am persuing seems to be working for the goal of making an item which changes it's apperanace based on number of items in a stack, however it's going to easily generate 3000+ files between predicate checking alone, if my math is correct. Any suggestions on how to optimize this so I don't have to iterate through every hotbar slot, and every inventory slot, check all seven varients of custom_model_data, etc.

Thanks!

I am aware this is not sampling every check that is needed for all the combinations, once I realized I was going to be making 100's of identical files with just a single value change, or filename change, I figured I'd better ask before I proceed further.
