Custom on-screen button for "pick block with NBT"

In Bedrock, Ctrl + Middle-click on a filled chest/dispenser/furnace picks it up into your inventory with contents intact (shows as an item with a "+NBT" tag). This currently only works with a physical mouse + keyboard connected. I'd like to ask if this can be replicated as a touchscreen-friendly button through an add-on: - Can a behavior pack trigger this NBT-copy behavior at all, or is it locked to the engine's input layer? - Does the Script API (@minecraft/server) allow raycasting the block a player is looking at and reading its container contents, so this could be replicated by giving a matching pre-filled item? - Has anyone found a working alternative already (e.g. NPC dialogue menus that give pre-filled containers)? Would appreciate any insight on whether this is technically possible for add-on creators, or if it needs to remain an engine-level feature. Thanks!
