Hopefully it’s all electronic. There should be nothing to make easier.
Meanwhile, why would you use a service that maintain privacy, while making choices to lose the benefit?
I used to do something like that a couple decades ago. I still have a domain with wildcard email forwarding, with the goal of using a different email for every service. Then I know who leaked my information, knew which password to reset, and who to block. But it wouldn’t be difficult to connect me with the domain, so one of the reasons I stopped using it was not seeing a privacy benefit (plus it was too much work).
Now that we have services to make it easy, let them do their thing. Every account ve created in the last 3 years has a unique generated email as well as a generated password. It’s all managed by a password manager so easy for me, and every time there’s a leak of my credential, I know which to rest or delete. I know which email to stop forwarding
