Rakuten Credit Cards Question

My wife and I are looking at getting Rakuten credit cards but we were trying to find out if we could get separate cards connected to our individual bank accounts under the same Rakuten account so we could both build up points as a household.

I understand there's a family card but from what I understand that would still lead to 2 cards connected to a single bank account. Would the process in this case be to apply for 2 separate credit cards for 2 separate bank accounts under one Rakuten account?

Thanks for any help!
