World Quest Item Command

Can you add a command that allows you to open a storage that you can store only Quest items in it
because some quests requires you to go to an island that might not have a bank and you might need to get a quest item with you that you forgot it inside your bank storage also it will waste your storage to store items that you don't really need it.

i currently have 10 quest items in my storage that wastes my space.

 

there have been made dozens of suggestions made about this issue. use a searchbar before making a suggestion.
Also If you don't have space in your inv just throw out ityems by filling your inventory and then replacing your quest items with other items (emeralds for instance) and then throw that item out. If you want them back just use /fixquests command.
