I had a similar problem where the end of a verse and start of the chorus needed the time it took 6 beats to pass. I used 3 bars instead of 2 and put the second hold chord on the 3rd beat of the 2nd bar. For some reason when I used the F5 way on the 4th chorus it didn't work out for me, could have been my error though. It may have been that I copied and pasted the bars with the timing changes.
