Autoselect SLA and Site for ServiceRequest based on User Site info

Autoselect SLA and Site for ServiceRequest based on User Site info

Is there any way to asign SLA and Site for a Service Request based on the user site that is requesting. This is possible for Indicent Request but i canĀ“t find how to make it works for Service Request. We have multiple Sites configured and as we can't do this for Service Request as for Incident the only workaround is to clone every service request for each site, set SLA and site on the service template, but the amount of templeate is a very long list and they are the same type of service, they are only diferent in SLA for sclalation.

Thanks in advanced.
 Regards.
