Upgrading to Realms Plus needs to be easier

I wanted to upgrade from realms to realms plus on PC, but having to view that billing through the Microsoft site offers no way to do that. Furthermore, it seems like the two service run independently of one another meaning you would have to cancel realms to get realms plus, offering no proration of that transfer, and making you start your server over. Regardless of downloading a realm and uploading it back into realms plus, this is making the jump from realms to realms plus a big roadblock for people. I would lose out on money AND have to do the leg work to re-setup my server.
