Hmm ... that idea fell at the first hurdle ... inserting two bars for a count-in didn't move the utility tracks by the two bars, so everythings misaligned.

Reverted, though it appears to have copied the bar text(?) into every other bar, so I now have 42 "Intro"s. Ho Hum. Quit the program and restarted it.

Looked to copy the entire song by two bars, but that too does not copy/move the utility tracks.

Obviously it's better to start out like that than try to change.
Oh dear ... try to regenerate Utility but lose the octave shift, can't set octave shift on a utility track. OK. Time out. Try again another time.
