For several years now I've had an American Express Corporate Gold card and had a Membership Rewards account associated with that account. Just this week I received my first Amex Platinum card. When I log in to view my MR account, I see two separate accounts...one for my corporate card and one for my platinum card. Before I can view the details or shop I need to select which MR account I want to view.

Is there a way I can merge these two accounts together so that points I earn on both cards accumulate into one MR account?
