Sharing this innovation lab idea that has been sitting in there. I was trying to solve for this exact issue and saw there were other similar questions in the community to be able to report on the amount of time an object is in a specific status. For instance "How long an issue sits in New status before someone began to work on it"... Let's see if we can get enough votes to get this one on the roadmap.

The Journal Entry report might solve that problem. I recently used it to figure out how long some projects have been on hold. I don't know if it would do exactly what you want, but worth checking it out.
