Named View Criteria with no wizard - I write the SQL

Question

Using JDeveloper/ADF 11.1.2.3.
Is there a way to create a named View Criteria with a SQL Select that is more complex than the wizard can write?
I know that I can write code to create a View Criteria at runtime, but then I can't just drag and drop it like a named one.
One use case:
I have a table named FACILITIES, with a detail table named FACILITY_SERVICES. I want a view criteria for FACILITIES that finds all facilities that have all the required services in a bind variable that is a comma delimited list.
WHERE list.to_vc_array(:requiredServices) /* I wrote this function to translate a comma delimited list to my own vc_arraytype. */
   SUBMULTISET OF
      CAST(MULTISET ( SELECT service
                        FROM facility_services
                       WHERE facilities.facility_id = facility_services.facility_id)
           AS vc_arraytype)With the wizard, I can't even write a simple IN query (match at least one of the required services), much less this more complex one (match ALL the required services).

I'm not sure that this is so bad :)
You need to implement one interface and override one method.
For example:
public class YourVOImpl extends ViewObjectImpl implements ViewCriteriaAdapter {
    protected void create() {
        super.create();
        setViewCriteriaAdapter(this);
    @Override
    public String getViewCriteriaClause(ViewObject viewObject, ViewCriteria viewCriteria) {
        if (viewCriteria == null || viewCriteria.size() == 0) return null;
        return "list.to_vc_array(:requiredServices)\n" +
                  "   SUBMULTISET OF \n" +
                  "      CAST(MULTISET ( SELECT service\n" +
                  "                        FROM facility_services\n" +
                  "                       WHERE facilities.facility_id = facility_services.facility_id)\n" +
                  "           AS vc_arraytype)");
}Dario
