Open Solo Notation

I'm making an arrangement of R.S.V.P. by David Kingsnorth, and I'm putting a drum solo after the head for an amount of time that isn't defined. I know that the way to do that is to just have a line taken up by a multi-measure rest sign without a number and to write "drum solo, to [wherever] on cue." I have no idea how to do this in Musescore, though. I'd love if someone could let me know.
