Customizing artist images in physical music library

I wish Apple would let us upload our own pics for artists in our own personal library. There are several very well-known artists that only have a microphone icon, and a handful of artists have incorrect pictures, such as Aya in the screenshot below (I assume in these instances there are other artists with the same name but they’re not the ones in my library). This happens when I view my library on my phone, iPad, and Apple TV.
