2 credit cards, each with their own unique logon ID & password, same bank

Sure can set up both for download. That's there's 2 at the same bank is irrelevant.

What IS relevant is "how many card statements do you get"?

If a single statement (which is my situation, 2 cards, 2 numbers, 1 statement) I only have 1 card setup in Q … and all transactions for both cards download into it since the bank (BarclayCardUS) knows it as as single account.
