[PAID] Store/Move the Backpack Item when not empty

[Flammable]

I'm looking for someone who can make me a simple plugin to store backpacks inside lockers when you have items inside. I know why Facepunch implemented this restriction. I don't want my players to be able to keep 10 backpacks full of loot inside their player inventories as well. But I want to SWAP full backpacks inside the locker properly, only in the backpack slot between the player-locker. Could there be a vanilla server command for this that I can use instead? Let me know. I hope this plugin idea is possible and inexpensive to create.

Hello,
