Remove visbility of custom music/mainstream songs

Hi, Can you please allow us to 'remove the visibility' of custom music/mainstream songs from our logins?
I have a client login that allows couples to choose a song - but one couple just emailed me asking for a covers song. I had no idea there were covers on your website! Let alone Barbie soundtrack songs... and now I have to go back to them telling them I can't licence it as its not in my subscription. What a pickle!
