Easy item access from shulker boxes and ender chest (survival)

I want to assign a shulker box or ender chest to an inventory tab in survival to give direct access to the shulker contents/items without placing it down.  Similar looking to creative inventory tabs.  There would have to be a limited number of tabs you can assign a shulker box to.  The name of the shulker would be the name of the tab.  One tab is your main inventory.

Example: Select your tab belonging to a shulker box and start mining.  Everything you pick up goes directly into the shulker inventory as you mine.  When it gets full, select the next tab and keep mining.   You don’t have to keep running to a chest monster to empty your inventory.

Example: When you right click on a crafting table or something with inventory, it would be nice to have the tabs available so you can select one and take things straight from the shulker to the crafting table and back to the shulker.

You still have your regular inventory with all the items,  shulkers and bundles.  Nothing really changes other than easier access to items in shulker boxes and the ender chest.

Analogy: Your regular inventory is a backpack.  The backpack can only hold the same amount as it used to.  Pockets of a backpack can hold one shulker box or an ender chest.  Only one pocket can be opened at a time.  Items can go straight in and out of the pocket. Shulkers are like pocket liners of a backpack.

I don’t want a backpack in the game, just an analogy.  I didn’t include bundles, but maybe something to think about.
