I want to measure the total number of transactions for an agent group in a timeframe and I want to filter out certain purepaths from that total. I've used the agent breakdown dashlet and filtered on the specific agent groups but don't know how to remove purepaths that I don't want from the total. The purepath filtering options are contains, starts with, ends with, and equals. There is no option for 'doesn't contain'. Is there a way to do this?
