Slash region symbol name?

I’m trying to figure out what is the name for the slash region symbol. I know it can be found here:

But what is the name that Dorico calls it?

It would be so helpful to have a list (or a exel -file) that would have the “Dorico names” on the left side and “SMUFL names” on the right side.

I found it!

It wasn’t a music symbol, but actually a “oversized slash notehead” in the notehead sets -editor.
