How can I create a smart playlist in iTunes that updates weekly?

I have about 1100 songs in my library from CDs in itunes which are matched in Apple music/iCloud music library. Some of them are loved in terms of Apple Music and others not. Here comes the challenge: I want to create a smart playlist with still not loved songs(love is none rule) limited to 25 and it should live update every week. What I’ve done is to set the following rules: - Plays < 15 - Love is none - live updating - Limit 25 songs But this will make songs never return back to the playlist. Do you have a better idea? Thanks in advance.
