stack size issues

so I have guns set to a stacksize of 1 but in many different crates guns can spawn in stacks of 2-3, is there a way to make them split somehow? because if they get right clicked into an inventory they stay stacked and there is no way to tell if a gun is stacked or not. Thanks!

or is there a way to show like the gun is in a stack size of 3? or make them split when they get moved into an inventory?

i realize also is there a way to show that certain items are stacked? like turrets is there a way to show a number like other things that can normally stack to show how many are in a stack?
