I have 5 types of Chase cards and when I try to add more than one Chase card in GoBank bill pay , there is no way to nickname the card or view last few digits of credit card to know which of the two cards you are paying.

When I called customer service, they said they are improving on it in next phase whenever Beta version ends.

To overcome the issue, when I pay the bill and payment is completed and posted, I delete the card and start all over again when new payment is due.
