We recently enabled the add-on feature for online booking, but are finding that people are booking their add-ons with a different staff member than the primary service. For example, one of our add-ons is a Toner Treatment that you can add to a primary service like a Haircut or Shampoo. We have had some people book the toner portion of the service with one stylist and the shampoo with another stylist. Currently, our multi-service rules are set to "can be split", so that people can book multiple services with multiple providers, but it would be amazing to have a toggle on specific services or add-ons for whether it can be split with other things or not. That way, we can make sure people are still able to book in with multiple people, but not for those add-ons that require being with one service provider only!
