[CONNECT C++] Item Types Pick List API

MicroStation CONNECT Update 7 documentation has some hints that Pick Lists are to be introduced to Item Types.  That is, the ability of an Item Types schema designer to add a list of possible values that an Item instance can store.

Can we expect to see an API for Pick Lists?  We already reinvented that wheel for AreaAnnotator, so I don't want to go any further down that route.
