We would like to filter the Insight CF with service desk request type, e.g.: 

• We have different services with a custom attribute: TYPE.
• We defined Service 1 which has an TYPE = Software attribute.
• We created Insight custom field to return those services according to the request type.We would like to define "Filter Issue Scope (IQL)" like:
  • Type = ${requestType}
  • So that, service desk portal user should only see the Service 1 in the select list when opens a request which is a SOFTWARE.
