Adding a Name to a Group of Staves/Naming Staves within a Group

I was curious to see if there was anyway in 4.3 to either add a name to a group a staves, or name individual staves when you add a staff to an instrument. I've attached a couple pictures from Mahler's 8th Symphony of what I'm looking to do. I'm currently working on a score that will include vocal solos, as well as a full SATB choir, and I'm wanting to add this text at the beginning of the score, rather than having really long Long and Short names. Below is my current solution:

Soprano Solo (S Solo)
Alto Solo (A Solo)
Tenor Solo (T Solo)
Bass Solo (B Solo)

Sopranos (S)
Altos (A)
Tenors (T)
Basses (B)

If anyone has a solution that can be done within MuseScore, that would be great! Thank you!
