I have tried searching without success for a recent(ish) post on this topic. I use CardPointers + (i.e. the paid version) to add offers to my five Amex cards, but I always do this by manually selecting which offers to apply to which cards. I've been doing it this way in order to ensure that the offers I am most likely to use are applied to the card where the purchase will earn the most MR points (e.g., Marriott offer applied to the green card for 3x travel) because normally, selecting an offer on one card will preclude selection of the same offer on a different card. However, I believe saw a post here suggesting that one can circumvent this limitation by using the auto-add feature on CP+ -- e.g., the Marriott offer would be applied to all cards where it is present. Does anyone have experience with this and if so can you confirm?
