Roon ARC: find local music to download

I wanted to selectively download local music from Roon Core to Roon ARC. However, there is no “local” filter available in Roon ARC. As a workaround, I had to disable Qobuz in to hide streaming content in Roon ARC. It would be nice if Roon ARC had a way to do such filtering.

Why are bookmarks not available in Roon ARC? A bookmark can be used to filter local content.
