Questions about playlists and Tidal

I have two types of playlists. One is for Tidal (composed solely of Tidal tracks) and one is for stored music at home (“Home Playlists”). I don’t want to use the Tidal playlists at home - don’t want them even to show in my Home Playlists. How do I do that?
I want only stored music to appear in my Home Playlists. Occasionally Roon will suggest improvements to my Home Playlists that would replace stored music with Tidal tracks. Is there a way to export a list of those suggested upgrades so I can see if I can acquire stored tracks with similar (or better) qualities?
