I am doubtful that Picard will do that.
Though I could be wrong.
However if you join Musicbrainz (which is something different to Picard), you can add Releases (meta-data from CDs/albums) to your Collections where they will be saved in your Musicbrainz account.
Here is an example of a Collections page on Musicbrainz.
Amongst other benefits of doing this is that you can get your tags semi-automatically updated for your whole collection.
