Mouse genitalia options when Character Creating

My options request is mostly with mouse/rat in mind, knowing mice/rats are popular creatures of science and are probably going to get Character Created a lot. I'll go on to suggest maybe even EXPANDED rodent/marsupial genitalia selections to include less well-known and more unique shapes instead of the usual feline/canine/horse/reptile/human. Echidna penis with its four heads, sugar gliders with its bifurcated penis and cloaca, etc.
