Has anyone with a G-70 figured out how to get a break mute (a silence to the next bar)?

Every other Roland arranger I have ever seen and used has had this essential button (can you think of a song that doesn't break SOMEWHERE??!!) and after poring through the manuals I finally found the feature is implimented in the MIDI specs, but seems to have no way of attaching it to an action or button. So if any smart guy/gal out there has figured this one out, PLEASE post with the workaround.

And if Roland Italy is reading this.......... PLEASE PLEASE PLEASE PLEASE PLEASE bring back a way to assign this ESSENTIAL feature to the assignable switches or foot pedals (or D-Beam or telepathy or whatever!).
