I agree that it may be a useful option.  Just correcting the anatomical correctness. :)

A JCM (Joint Controlled Morph) is a Poser master dial connection.  Despite the name, it is not the Joint channels but the associated Rotation channels that are used.  So, you connect the morph(s) as slave to one or more of the rotation dials as the masters.  This involves putting a valueOpDeltaAdd section into the slave (the morph (targetGeom) channel).

Genital switching involves two (or more) geometries used with an Alternate Geometry dial (geomChan).  Basically, in this case the original full geometry has the genitals or not and then you have just the group in the alternate .obj file set up in the CR2 as such:

alternateGeom section in the bodypart Actor section with the .obj group.
geomChan section in the channels section with settings that make the selection discreet.

If you need more specifics, they can be provided.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
