Deleting multiple performances

Does anyone have an easy way to delete multiple performances in one fell swoop? Use case: When you make a mistake while running the Product Creation tool and create a large number of performances with an error that cannot be updated through Season Manager.

I was thinking about trying to mess around with TP_DELETE_PERFORMANCE in Test, to see if I could make it work for a set of performances, but wanted to check if anyone else already had a solution.

Thanks!
