A good bit of servers I know allow you to click on a storage item with another and if it doesn’t fit, it begins a do_after to transfer the items into the other, it would make CM inventory a bit less hellish.
ex: you click on backpack with a toolpouch and it dumps the contents of the toolpouch into your backpack
ex 2: you click on a webbing with a injector pouch and it dumps the injectors into your webbing
