iTunes My Music to Apple Music Artist link
just noticed this message after it has been posted a long time ago, anyway here's my answer:

In iTunes artist view (top tab, 'My Music' selected and 'Artists' selected as grouping) select one artist on the sidebar on the left. There are three small tabs just below the artist name after you select one. If you click on 'All' it will show all music from that artist, including apple music (see screenshot below).
