Having dynamic item damage in loot tables in 1.16

Anyone knows if there is a way to give items a dynamic amount of damage (based on scores for example) in minecraft 1.16. For 1.17+, I can use either the copy_nbt field from a previously modified storage or the set_damage field with scoreboards but I can't figure out a way of doing it in MC 1.16.
For a bit more context, what I want to achieve is an item with a custom durability. The thing is that the max number of uses can be configured through a score and thus I don't know beforehand how many uses there are.
