Yes, as previously mentioned, only cards listed FS/T can be included in the transaction manager. The options would be to have the other member move said cards to FS/T or use the "propose a transaction" button and instead of selecting them, use the text fields and list the cards you are interested in. They would not be added to your collection automatically this way though. Just depends on what the other member is looking to do.
Matt Kenseth card collection is nearing 50% with over 2300 different cards. Always looking for the missing remainders to get to 100% completion.
