@ Peter: This sounds quite similar to what we have done  in the PEPFAR
system as well, except we have about 1400 data element + category option
combos in one of the bigger indicators. It was not of course possible to
define these through the user interface, but worked fine through the API.

@Jane : Good to hear that it works for you. We'll be sure to include a
regression test for this to be sure this continues to be "supported".

Regards,
Jason
