writing for voice, but with different playback sound

I am relatively new to MuseScore. Used to use Finale.
I am writing for my male a cappella group. I want 5 parts...a lead voice, then Tenor 1, Tenor 2, Bari and Bass. I want these to be the labels when i print the part.
When I playback, I do not like the "voice" sound. It is way too reverb-y. I can't make out the individual notes. It is not helpful. Unless i can change the sound of the "voice", I want to have another instrument for playback. When i used to use Finale, I used the sound of tenor saxophones for all the male voice parts. It worked very well. I could change the label to what i wanted.

But i want to write as if for an instrument in the key of C. Not a transposing instrument.
Often, I am copying some notes from a piece of music that is not transposed. When i used Finale, i could write as if for a voice (not a transposing instrument), but have it sound as a tenor saxophone.
Can i do this in MuseScore?
I have tried using instruments in "C", like a flute, but they are not as clear in playback as i want.
How can i write as if for voice, getting the correct labels when finished, but hearing the tenor sax for playback while writing? (Please tell me this is possible...)
