I like playing guitar to BIAB backing tracks, and if they have a melody line I play the guitar tabs on the notation.

I've learned that the tabs are shown for the instrument that is playing the melody line, which makes sense. However, sometimes I forget which instrument has the melody, or it may be an orchestral piece where the melody may be from any one of a number of instruments.

So, my question is, is there a way to force the tab to show no matter what instrument is playing the melody line?
