Well you can just change the tag on the portal to make it connect to a different one.

Careful with that, the change takes a few seconds to process and you can easily send yourself to a portal that's just about to be cut off.

That's why I have 2 portals at the 'hub', since 1 always has the same address I can always dial back to it unless I've really screwed up and left it with another connection active.
Even outside of dialing errors with the service portal (happened a few times for sure) it's also useful for when I end up travelling between other portal locations on foot.
