Modifying or cancelling a plan program
If you need to modify a program within a plan, simply click the name of the program you want to modify, and it will take you to the program interface.
However, if you added an existing program outside of the plan, you can modify the source program, and all changes will be reflected within plan. So if you scheduled the same program multiple times, you only have to make changes once.
To delete a program, simply hover over the name of the program you want to delete, then click the "x" button to the left of the row. This will remove the program from the plan and delete all of the program's sessions from the calendar.
