Individual Part labeling - Barbershop style

Hey all,

I use MuseScore primarily for barbershop quartet music. For those who may not be familiar w/ the score layout, it's 4 voice parts on a two staff (1 treble clef and 1 bass clef) closed score w/ 2 voices per staff. The top voice is the tenor, the second voice is the lead/melody, the third voice (top bass cleff voice) is the baritone and the bottom voice is, obviously, the bass. The tenor/baritone voices are stems up and the lead/bass are stems down.

For those of us who like to arrange, the Barbershop Harmony Society wants us to make sure the voice parts are labeled "Tenor, Lead, Baritone, Bass" on the score. However, using only 2 staves, Tenor and Bass, I get only those part names to the left of the top system. How can I change that so I can have all four voice parts listed, rather than just the 2 default voices?
