It does not but here's a work-around:
1. Create a duplicate Schedule of what they are using.
2. Switch the current Schedule with the new one.
3. Finally, disable the new Schedule.
You can change Schedules from the Task panel. Check the Target item and click on the Edit Schedule link at the top of the table. Alternately, you can have the author republish the report and you tell them to select the new Schedule.
