"Repeat last measure" shortcut (without having to select last measure)

If you want to duplicate the previous measure, and you're in the middle of Note Input, you basically have to come out of Input mode and select the last measure and then press the Repeat shortcut.

What i need to do is simply duplicate the previous measure (without selecting), staying in the mode i'm in and in the note position i'm in (in case i want to edit the copied data).
