I have successfully added an Exclusion Script and tested the Triggered Send using different scenarios
(ROWCOUNT(LOOKUPROWS("MyDataExtension", "Environment", Environment)) < 1)
OR
(ROWCOUNT(LOOKUPROWS("OtherDE", "Variable", Value)) < 1)
However I'd like to add it to tons of other Triggered Sends....
I'd desire to avoid doing it manually as I have too many, Is it possible?
