Delete all strength exercises on edit page

Here's something pretty simple that would really help me, although it is by far not pressing. 

I'd like a way to delete all the strength exercises for a day on the edit page in one fell swoop.  Since I love to plan and tend to change my plans occassionally, I find that I need to replace my strength workouts sometimes.  Instead of deleting from the Blog page using the Move/Delete/Copy tool and then having to go in to the edit page and add the new workout or clicking the checkbox next to every strength exercise to delete them in the edit page, it would be great to have a Delete All checkbox or button to save me some time.

Like I said, not major, just something to make it easier on those of us that change our plans
