Feature request: customize the name of the Root CA added to the trust store

mkcert currently sets the name of the Root CA certificate to "mkcert user@host"; at least that's what I see in my Trusted Root Certification Authorities on Windows.

Would it be possible to customize (even partly) the name (e.g., adding a custom suffix)?
In my case, for isolation purposes, I generate multiple Root CA certificates for each environment of my application. Of course this is only used on the developers machines, but it would be nice for us to be able to distinguish the entries.
