Remove the "." on my penname so it will automatically link with my Amazon profile

[Cassandra]

Hi! My pen name is Cassandra M, but my Goodreads profile is Cassandra M. with a period after M. So books released on Amazon don't automatically link on my profile. Is there a way to rectify the Goodreads error without compromising the books that are already connected to this profile?

We use punctuation on initials, as is standard pretty much everywhere. Correct your name on Amazon if you'd like smoother linking.

I understand it's common, but my pen name doesn't have a period, and I would rather not change it to M. with a period.
Is there a way I can change it here on Goodreads?

It is site policy to have it there.
