Since you are asking about Citrix Netscaler I wanted to mention a new feature Automated Policy based Routing(APBR) and RISE(Remote Integrated Service Engine) that is available on Citrix Netscaler which might ease you pain points in configuring services.
Here are some details and links
RISE (Remote Integrated Services Engine) is an innovative, industry-first architecture conceived by the Nexus Services engineering team to seamlessly integrate Nexus switches with appliances offering L2/L3/L4-L7 services. RISE makes the service appliance look like a line card in the Nexus 7K series. This integration allows any appliance to take advantage of the benefits of an in-chassis module such as increased application performance, high application availability, and data center consolidation.
