Service groups are a great way to cluster On Request services together. Commonly used for Roll Off services.

For this example, I have created a 15Y Roll Off Service Group. These services can still be used individually, however by combining them it will allow you to schedule all necessary services Delivery, Dump & Return, Final all at the same time.

Customer has requested a 15YD for 30 days

With the service group, I can select the group, set the delivery, 3 Dump & Returns and Final all in the same scheduling tab.
