TRANSPOSING JUST ONE VOICE

Dear everybody!

excuse my english, if there's a case\
well, the title is already explaining itself, so can it be done under windows 7 with my 2.0.2 version without copying the voice, transposing and copying back - which is quite complicated too, cause it pastes as the first voice; actually that matter stands alone as an other topic - ?
i'm pretty noob using the program, thank You in anticipation
