When distributing a compilation if you want the releases to show up on the artist's newest release section as well as have the artist pitch, each track needs to be sent out as a single to Spotify only.
The reasoning for this is because only the main artist on the album & track levels can pitch.
What you will want to do is create a new release for the singles usually, we see users use the same catalog number as the comp but with a letter after it, so the first single would be CAT001a.
After setting the release up on the album level, you can copy all the metadata and wav file from the comp by selecting the "Copy track from other releases" as the upload method.
This is important to do as you want the ISRC to be the same so that the tracks link up on Spotify.
After you have imported the track, you will select the release date and hit distribute release, next you will be prompt to choose the stores, you will select the "unselect all" button at the top and then just select Spotify and distribute the release!
