OK, here's what I did. Fairly straight-forward once one knows.

I set the song to two choruses and unfolded to get a one-chorus song of a double-chorus length.
I did copy-special from...to create two new double choruses, inserting the bars and transposing up each new chorus by two semitones.
I then did a Transpose from...to to transpose the third chorus up a further semitone.
I set the chorus start in the main control to the second chorus, and I set the length as that of the second chorus, which greys out the third chorus.
I set the chorus repeats to a multiple.
I used Edit->Song form to set the third chorus as a tag.
I removed the turnaround from the end of the tag and tidied the song ending.

That seems to have worked out pretty well.
