RCM now allows you to set up Utilisation Rate records against specific locations. To access the Utilisation Rate table, go to System Setup >> Rates >> Rate Utilisation.

Utilisation Rates allow you to apply increases or decreases in the price of new bookings, based on how much of your fleet is already booked. This new location field allows you to create Utilisation Rate records that only apply to bookings made in a specific pickup location. The selected location will appear in the Location field on the Rate Utilisation table, and those records set against All Locations will have a blank space in this field. 

For more information on how they work, please see the Rate Utilisation article.
