Edit Song Form

How does one edit a song form? For example, I wanted to change Stella By Starlight from:

A (16 bars!)
B (8 bars)
C (8 bars)

to:

A (8 bars)
B (8 bars)
C (8 bars)
A2 (8 bars)

Thanks.

I've figured out (via the symbols key in editor) how to get the section letters (i.e., A, B, C, etc) but is there any way to indicate alternate sections, ie., A2?

You can use the text feature, enter a "2”. Then using the up/down buttons, raise the 2 level with the A-rehearsal mark. You can adjust the position of the 2 using the space bar (inside the text field).
