Obvious further development from stack splitting: full stack transfer dragging

I would really appreciate to see a keyboard shortcut for transferring full stacks.

Example: I want to load 7 x full stacks of material on my mule. For every material I have to drag it into the transfer window, click "max amount" and confirm.

Suggestion: Just like splitting works with the Shift key, I would love to see a Ctrl + drag option, moving the full stack (regardless of the actual amount) to the transfer window without any further prompt.

Without having any information about how GW is coded but seeing the shift-split update makes me hope that a ctrl-full stack update shouldn't be too hard to implement.
