Well, TTBOMK, Schedules Direct doesn't have anyone who's doing any 
custom programming and we're just making a direct connection to TMS 
(and, therefore, get only what TMS offers).  AIUI, Schedules Direct is 
currently just the entity that handles individual users/authentication 
and TMS handles all the data.

Now, 4 years ago, they asked nicely, but I don't think anyone was 
interested...
