Let Pick Block tool pull from shulker boxes

the block pick button should be able to pull items from shulker boxes.

When working on large projects, running out of inventory space to hold materials is quite common, and placing down a shulker box to grab more only to break the box again is a little bit annoying. By pressing the pick block button I can grab more of a specific item from my inventory, and what is a shulker box but an expansion of the inventory?

I see two ways this could be done.

1- The pick block tool scans all shulker boxes for the item and grabs the first one it finds.

2- the pick block tool can only grab items out of a shulker box in the player's off-hand.

This very small functionality would make the pick block tool and shulker boxes even more useful, and would be a nice quality of life feature to have.
