Allow custom answering rules to override main call handling rule. Example: Holidays

Currently for a holiday I have to create a custom answering rule for said holiday, but to use this custom rule I have to turn off the main handling rule and turn on the holiday rule. There should be a check box that allows the holiday rule to override the main rule for the given dates and then pass the validation check. This will allow me to pre-program all my holidays in January and never have to turn anything off and on. I currently have to set alarms reminding me to turn off the main handler and turn on "Memorial Day". If I forget to go back and swap them after the holiday the message will continue to run until it's manually turned off. Please help us out here!
