We would ultimately like the option or a setting to require services on an appointment to start at the same time.

Our business has services we offer, and we have additional services we would like clients to be able to book / add that would happen at the same time. We currently utilize Service modifiers for this, however modifiers aren't tracked in reporting. Additionally, if a client has a voucher for the service the modifier was added to - it will set the service cost to $0. This results in our needing to add a retail product to the sale so that we can charge for this additional service.

The current workaround of requiring clients select a guest to add to an appointment for an additional service in order for them to start at the same time is not ideal. We cannot expect clients to know that they must select a guest online to accomplish this. There are repercussions on our end if the client does not follow this workflow.

If there was an option to ensure that additional services added to an appointment have the same start time (instead of back to back) without having to group book, this would be ideal.
