I use Apple Music, but have purchased music for a Family Member on my Account. Can I separate the two?

So I have Apple Music and I have used my account to buy music for a younger Family member (they had iTunes cards) to put on their iPod Touch. Now I don't want the songs on my phone since I'm using Apple Music, but I when I go to remove purchased items, it says it will delete it from all of my devices. I don't delete them, not wanting to delete it everywhere else. More specifically the computer used when they get more music. How can I remove the purchased songs without deleting it everywhere else, so that it's still their when the family member in question plugs it in to the computer and gets purchases later on?
