Feedback / question - Multiple Cores for Arc?

On the Arc home screen, I now see both my cores listed. Now I can only access the active core, the other one is listed as “last seen X hours ago” (where X is where I arrived at my second home and activated the core here, and deauthorized my primary home core). Feels like it’s getting closer to the idea that I might be able to be link Arc to my primary core so that I don’t have to wipe all my downloads every time I move between cores. Just hoping / guessing.
