Another way might be to write two sets of changes at the same tempo.

The first set lets say will be the chords you will place on the 'and' of each beat. Yet just write them as if they were normal 4 to the bar.

You then copy/move tracks bouncing this chord part over to a spare melody or soloist channel.

Then erase the chord sheet and write the second set of changes; the ones that'll sound 'on' the beat.

Go back to the first set on the other channel then time shift them ahead by 55/60 ticks or whatever works best for the feel and style you're working in.

They should now fit exactly in between the on the beat changes.

Can sound a bit stiff if you don't push them ahead by the right number of ticks so experiment. It can useful for short riff phrasing you can't find in the style you're using but which you need for the song.
