If I remember correctly, there is no search feature on Carbon except for people whoa re on your buddy list, so there is no way to search for what tables your opponents are playing without putting them on the buddy list. You are only able to play on 4 tables at a time on Carbon, so it shouldn't be that difficult of a task to do while playing. IMO, no one will make a product like TST for Carbon because there isn't the mass multi-tabling like on other sites.
Also, how many sites did you post this exact same question on? Just a little googling about some exacts and I found your post on 4 other forums...
