Reverse of a Birds mouth router bit?

[JDuke]

Id like to streamline the cutting of a 90 degree angle on the edge of a board that is off axis enough to use it as a flat piece of crown molding

   

I know I could do something like this with 4 cuts on the table saw, but I’d like a router bit that would cut each side in one pass.

I am sure a bit like this exists, what name does it go by so I can search for it?

Thanks

Crown bevel bit,  Freud #99-421.   This is a large bit not for hand held router use,   Not cheap.   Roly

Thank you both,

I knew the profile existed but kept coming up empty using the wrong search terms.
