Invert chord command

I wish there was a invert up/down command. Invert up would take the lowest note up an octave and vice versa.
Especially when doing this with the mouse, I have a hard time selecting a specific note in a chord by clicking, it seems to sometimes select the whole chord and sometime only one note. Is there a way to do this selection by mouse in a more controlled manner?

You can create binds (or use the Jump Bar) for Filter Top/Bottom Notes. I use Alt+1/2/3 for Top/Second/Third and Alt+4 for Bottom.

+1! Have been wishing for this for a long time.
