By clicking the heart icon in the top of an artist tile, you can save their profile as a favorite. This artist will appear in the top of the artist roster page in a new section called Favorites. This should help you easily access your most used artists profiles.
Note: You will now only receive push notifications for “favorite” artists. To cut down on any push notifications, un-favorite those artists. Also, make sure your Artist Growth apps are set to "allow" notifications.
