I've also been in CBS for a few years and haven't seen this option. But what we do as a work around is that in the Transactions and Fees, I set every waiver pickup to be $1. I never collect that $1, but I use it to track transactions and based upon it, warn owners if they're getting close and in 1 instance in 5 years have used it to retroactively undo one owner's 5 or 6 add drops at the end of the season. The nice thing about it is that everyone knows where they're at relatively to the league limit.... although it took one guy 3 years to catch on that it was there and that he was needlessly tracking his add drops on paper.
0-3 to 4-3. Worst choke in the history of baseball. Enough said.
