Add 2nd email address to exisiting Category

I added a Bank category for *** Email address is removed for privacy *** and was able to automatically have every email noted as a Bank for that back.
I also have emails from *** Email address is removed for privacy ***. I select one of the emails from *** Email address is removed for privacy ***. assign it to the Bank category and there doesnt seem to be any way to have all other emails from this bank catergorized as Bank.

Is there a way to do this?

Thanks
