Applying attribute combo to event/tracker programs

Are others using attribute combos (like projects, partner, or funder) for tracker programs? I am starting to do that in order to filter by implementer. I want to be able to use the dashboard filter rather than creating a million indicators or filtering in event reports. However, the way it’s set up, the attribute is assigned at the program stage and not at enrollment. That has meant that program indicators using TEI or enrollment count do not work (do not show the “disaggregated” data by attribute), only event counts.
Curious if others have done this and have general tips or specific tips on the program indicators.
