I think that my question might have been unclear. The situation is this: I've got an existing Marriott Rewards account. (Gold Level Club Marquis.)

This account has a substantial # of points in it.

I would like to take this same account and enroll it in Courtyard Club. I'm told that that is not possible. If I want to enroll in Courtyard Club, I've got to open a new account. (Which will be another Marriott Rewards account.)

Has anyone been able to take an existing MR account and add the Courtyard Club membership to it?
