Can I add text that shows on the screen, but not when printed?

I assume the title already says it. I'd like to add text in a score that shows on the screen, but not when the score is printed.

Here's why:

I often prepare sheet music for auditions. Right now I have a funny remark that I'd like to toss in, but I easily forget things, including funny remarks. So I'd like to add the remark to the sheet music as text. But the sheet music is also tailored for auditions. I'll also print the sheet music and take it with me to the audition where an accompanist will play it. It would be awkward if I hand over sheet music with these remarks in it.

I checked all types of text in the Palette under "Text". There's one that doesn't print, it's the S in the box, but I wasn't able to change the S into other text.

Is there text that I can add, but that won't be printed?

If there isn't, I'll have to delete the funny remark just before printing, but as I said ... I easily forget things, so I'll probably forget that too. :-P (joking)
