Entering percussion notation to an instrumental (not percussion) part

I have a situation where all but one player in the score switch to clapping. What is the best method to input the correct notehead and playback?

Personally I would just notate them normally, once you’re finished select the whole clapping part, right click > notehead and change to probably Crosses > X noteheads. If you don’t want them to play, go to the properties panel below and select suppress playback.

Thank you for your input. What you are suggesting is something I can do, but I am curious to find out how to make it playable with the clap sound as well.

See if using cues and hidden instruments works

for you. (You will also have to find a legitimate Clap sound, of course.)
