Http Service call with multiple parameters

Dreamfactory v2.9.0

Using HTTP Service type, my Dreamfactory is connected with an external web service.
Currently, if I pass one parameter to the service, it returns the data correctly.
However, if I pass multiple parameters to the service, it returns an error “Parameter ‘q’ was specified more than once”.
Example: http://localhost/api/v2/{serviceName}?q=value1%20value2

Is there any way that I can configure the service to allow multiple values for a parameter?
