@support, on the composition page the “Performances” column is hidden by default and you have to enable it.
Once enabled you see how many performances you have of a particular composition.
But I want to see the “zeros”. I want to see where I have a performance roon has not been able to identify as a composition. The reason is that then I can use this screen more systematically to fix my library. Slightly re-wording the performance title or adding a catalogue number often leads to a composition identification. Anything that is left I can systematically batch up and send to roon to complain to rovi about Instead of the more random drip-feed that is the current process.
I cannot see how to do this. Am I missing something or is this a feature request?
