I’m in a similar situation (My company uses our own product internally).

The approach we take is:

- We dogfood our changes by setting up a Trello board with the tasks that need to be done and just work through it.

- Progressively rolling out changes to beta groups until we think we can go to 100%.

Not sure about the internal reporting thing though, that seems like a visibility issue into product ownership. I’m sure someone in support might have a better idea on that as they probably deal with similar problems for external feedback.
