link parts and changing clefs

I would like to make two tenor parts (part A and B), both linked to the same tenor voice in score. Part A will be in “bass clef”. Part B will be in “treble clef 8va bassa”. And then export parts to PDF. In other words, I want to give the tenors their choice of reading in “bass clef” or reading in “treble clef 8va bassa”. I want any changes in Part A to trickle over into part B, and vice versa, EXCEPT for the change in clef sign. How could I do this?
