alternate endings in Tabledit

OK, Tabledit experts. I don't know the precise terms for what I want to ask here, but stick with me.

I am tabbing a song in AABB form. The A part has one ending when it repeats and a second when it moves on to the B part. I have figured out how to put the repeat signs in Tabledit, but not the brackets above the measures that indicate 1 for the first ending and 2 for the second ending.

Any help out there?

If you know the precise term for the brackets above the measure or for this general phenomenon, I'd like to know even if you can't help me with Tabledit per se.

Much obliged,

Dusty
