Unfortunately, I think what you're referring to is the need for track level metadata in Sooloos. This is one of the most requested features, I believe.

We had a promise that something was in the works a year or two ago, but nothing has materialised within Sooloos yet, although I believe Roon might have it.

I might be out of date though, so I'm sure others will chime in if I've not described the current state of affairs accurately.
