Overview: If you need to perform a bulk delete of several games at once, use the following action. Please use with care...measure twice, cut once.
Steps:
1. Export a copy of the current schedule (from the Competition's Schedule page)
2. Remove any rows in the file with games that you wish to keep. Only leave rows with games you wish to delete.
3. Add a column to the end of the file with the column header titled "Action". And for each record you wish you delete add "Delete" to the field in that row, per pic below. PMatch the exact letter casing for both words.
4. Import the file, and it will remove those games from your schedule.
