Rhythm kicks over notes for jazz lead sheet - hiding ledger lines

I'm trying to enter slash notation above standard notation as seen in jazz lead sheets - something like attached picture. I think I have it mostly figured out but if there's a better way let me know.

I'm entering notes in voice 3 and changing the note head to small slash. I'm left with a slash notehead with a ledger line. How do hide the ledger line for a single note?
