Adding to this. Would like to be able to go into a transaction for a specific vendor and see what the best card recommendation would have been. I pay my water and electric bill plus several other vendors I use online and currently I just continue to put them on the same card I always have because I dont have a way to tell if I could have gotten a better result and vendor search doesnt include online vendors. This would be a great way to leverage transaction history to fill the void left by not having all possible vendor and CC provider category information as we can use historical data to guide decisions.
