Additional Backpacks

Feature description

For example, a Quiver command '/quiver' and its head shortcut (ideally for the player to be able of removing it from their Inventory), this backpack by default would only allow Arrow Items to be placed inside, and would only have one row.
Similar additional Backpacks could include
A Pouch '/pouch' that only admits Potions by default
A Lunchbox '/lunchbox' that can only store cooked/prepared food items.
This would be backpack Types, following the current system of 1 Backpack by player.

How the feature is useful

The ability to create new backpacks with their own associated command, and the possibility of removing their shortcut from the players inventory would greatly open up new possibilities for delivering custom storage.
Using the command again could be the solution for the player losing the Shortcut.
Or just making it craftable.

This can be tied to my other idea of "Individual Backpacks".
So, the "Quiver", the "Pouch" or other backpack types could be craftable, and would preserve their contents on death, with the players being able to carry different types with them, but not 2 of the same type if both have items.
