Feature Request: Weapon Swap in Sell to Vendor Window

Ok, I realize the engineers at POE are literally hours away from a new league launch but this is apparently not on anyone's RADAR and hasn't been since I started playing but...

1. Is it impossible to make it so I can weapon swap when I'm trying to sell stuff to a vendor?

2. For that matter, is it possible to make it so I can swap out equipped gear and gear I'm carrying when I'm selling to a vendor.

Too often I'm carrying extrac crap in my weapon swap slots or I'd like to compare or swap out gems while I'm unloading stuff I no longer need to a vendor but I've got to exit the vender interaction to do so.

Am I the only one who'd love to see this?
