Merge all, merge to stack in estate

We've had the ability to merge stacks in inventory and storage for eons. How about allowing a merge to stack in estate so you could say store all your stackables in estate and just merge to the stack from inventory instead of having to drag and drop all the time...

I do like the change in the new way of things so double clicking items in estate picks it up, but could be annoying if you have a bunch of stuff in estate and accidentally double click wrong place.
