As far as I know most of the guys that are using a router to edge shape boards for edge gluing are using straight router bits. I usually do mine on a table saw, and then run them over the jointer.
There may be a router bit as you describe. The best way would be to check the various router bit supply stores and see if they list a profile like that. Try googling router bits, and see what comes up.
