Players can only use a single item, use after cleaning items
An example, the player has 10 items, when the player run the command after only 9 items left.
Sorry for my poor English.

ItemJoin v3.7 has been released and you can get it here;

This has been added as of v3.7 :D

Ahhh So items that have single command uses, and so once the command is ran it will remove x1 of the item from the players inventory. Is this what you mean? If so it is very achievable and I could easily get it out for v3.7

Yes,thank you very much.
