I'd love to be able to do this with AMEX but it seems like there is a ton of confusion about what we're asking. 

What makes this even more frustrating is that I have one client where this works and I can't figure out how we pulled it off. Still AMEX too. There are 5 different company cards and they all roll into a main GL account. The description says who made the charge, but they're all happily lumped together. 

Other client - Two AMEX cards and the only solution I can get to work is subaccounts.
