Create sub-folder with Quick Move

I’ve just moved over to eM Client having previously used Postbox.

The one killer feature for me is the quick move. Single key press and start typing the destination folder to file the email is brilliant!

As I recall, in Postbox I could at the same time create a new sub-folder then file the email in there. In eM Client it looks as though I have to set the folder up before I can use it.

Does anyone know if this is the case please? I’ve looked through help, FAQ and the menus but can’t find anything!
