Add a check box to the Schedule Manager for "Only Send If Not Empty."
I have a large number of reports we run on a daily or weekly basis to address important but not critical or urgent matters - things we don't need an alert for every issue, just one periodic summary so we can clean them up all at once if need be. However, it is useless for us to receive these reports in email when they are empty. Better to only receive them when there's actual data in the report. It would be nice if the Schedule Manager had an option to only send the report if the contents are not empty.
