Additionally, it would be useful to inhibit selected service types from being bookable during the primary service's processing time. E.g, this processing time, services assignable are service types Haircuts, Shaves, Waxes but NOT Chemical Services, Color Services.

In the case that a service is 5 hours, there is likely a chance that there are multiple instances where double booking can be utilized, but at current Boulevard only allows a single processing time to be added (manually or by default). My goal would be able to add a 30 min processing time after the first 30 min, followed by an hour of finishing time, and now again another 30 min of processing time followed by the remaining finishing time. The current workaround would be to create a secondary service to get this accomplished, but this requires complete manual manipulation of the schedule and confusing clients when their emails and receipts show multiple services for a single service.
