I'm not sure I follow you. I am using the repeating Chorus feature for the solo choruses. I am aware that for a song with one chorus, you cannot have a Tag. I can create the Tag just fine. I can even hand-enter my melody into the Tag.

I can successfully Copy my melody into the TAG, but BIAB then assumes that the TAG is now to be included in the main chorus. Since this is not what I want, I reset the chorus to end where I want it, and the melody in the Tag disappears.
