Save item type in game cache

I created a nice extended inventory system but unfortunately it works for only one unit.
Is it possible to save the item type variable array in the game cache and then restore it? (If it is possible how can I do it?)
If you have any other idea how I can use this system with more then one unit please tell me.

no, just replace the array with a gamecache mission.

You should not remove items and create them, you have to hide items, because otherwise custom values and attached variables to the items will be lost

Also, for some lame reason units can pick up hidden items, so better move them to a safe area of the map.

or don't order units to pick up hidden items
