/place jigsaw thing otherthing 7 ~ ~ ~

Hey I'm making an infinitely generating structure with jigsaw block but because there is a limit I need to make this command : "/place jigsaw thing otherthing 7 ~ ~ ~" on some markers that I've spawned in a grid pattern. but when you use this command, the first jigsaw block generated has a random rotation. which sometimes offset all the structure and I don't know how to fix it.
