Building chords from the top down

Is there an easy way to build chords from the top down?

I'm not sure - and also I note that there may be an easy note input method coming "borrowed" from Finale in 4.4.5.
I can do chords downwards - but it's a pain and takes too many key strokes.

So if I want an F7 chord to harmonise with an E in the melody - below it I need to do the following.
Input F + shift - which puts an F above the E, then do CMD/CTRL-down arrow to put the note below
I then have to make sure I'm still in the same space, and repeat for the A and C in the F7 chord.

Essentially I just want named notes below the melody not above.

I don't think that a simple way exists in MU4 right now.
