YOY Subscription Movement

Hi everyone!

Has anyone created a dashboard that shows movement of subscribers between packages?  For example, in FY20, 50 constituents had a Full Philharmonics subscription, but in FY21 45 renewed their subscription, but 5 moved to a different package.

Is that possible? I can clearly see how it would look in my brain, but I'm not sure how to translate that into Analytics-talk.  Thanks in advance!
