There is a way, Bill.

Ted, when you did this song, did you use the CONTROL track for expression, etc? If you did, then just go into STEP RECORD, bring up the CONTROL track and remove the RHYTHM START asterisk where it is coming in on the second beat instead of the first beat by clicking on ERS, (erase) then go to the beginning of the measure you want the rhythm to start and press the START/STOP button and your rhythm will start exactly on the beginning of the measure.
