Rhythm Notation for lead sheets

[Interesting: When I added the attachment, that was all that was posted. Here's the actual feature question]

I see drum notation, x-notes, so there's that. But sometimes, when I'm trying to prepare a quick lead sheet for an accompanist, all I need is, say, 4 slashes to a bar, with lyrics below, and chords above. Having to write the melody is not only more trouble, but it's also misleading. In jazz, it's improvised. I've seen entire concert books for which the pianist has chords and 4 slashes per bar, and that's it. He just needs to know cues and maybe lyrics. I'm a songwriter; I'm trying to do that same thing. It's just a step up from writing chords over a lyric sheet, except it does offer a time signature and a clearer indication of where the chords change. After I've settled on the melody, I can go back in and notate it.

Do you have something like that? The slashes? I don't see it.

Thanks!
