Is your feature request related to a problem? Please describe.
I'd like a single place to see all the territories to which I'm subscribed, so I can easily review and revise my subscriptions. Similar to the user settings > subscriptions page, where you manage subscriptions to individual stackers.

Describe the solution you'd like
A clear and concise description of what you want to happen.

I guess I kinda put that in the above section.

Describe alternatives you've considered
Looking through all territories and seeing if I'm subscribed, one at a time.

Additional context
I imagine this could be just like the user subs/mutes tabs on the settings page today.
