synchro start MIDI

[Lacko]

On SX700 I have one Registration Memory button set to synchro start not only accompaniment, but also a midi file. When stopping playing and then pressing that RM button again, midi file continues to play from the positions where it was stopped (not from beginning). I have to press Rewind button to get that midi file to its beginning. Is there some setting which enables to press just RM button to start midi everytime from beginning?
