If your piece of music permits it, use RealBand. It will still be some trial and error. You may put the first chord on a different track (using the same instrument) and the second is on the regular track for that instrument -- pushed back a little to achieve the effect.

I haven't tried it, it's just wild guessing that it might work. The general public will not hear the jerryrigging.
