I published the only possibility (as far as I k now) to enter more than 4 chords to a bar quite a while back.

It was by dividing a 4/4 bar into one 2/4 bar and one quarter note triplet (= 3/4) bar. This way you can enter 5 chords into one 4/4 bar.

The length of the half 3/4 bar has to be time adjusted, as it should last just as long as the 2/4 bar.
