Managing my collection

Neuropain

I have some question regarding what I can and can not do regarding my collection as seen in Strawberry.

Is there a way to make it prioritize a certain file type if there is more than one for the same song, say if I have a song in both mp3 and flac? I would like it to only show the flac file if there are more than one version of a song.
Is there a way to prevent zip files from showing up in the collection? I have some albums that I've gotten from places like bandcamp in archives, these are added to my collection even though they can't be played.
If there is no way to do either of these, is there a way to prevent a file from being shown in my collection without moving it somewhere else?

Thank you in advance.
