Adding Resources in Service Catalogue v Tasks

Hi. Currently we have the ability to add resources providing check boxes and question options in the form design for Service Requests. The resources are useful from a read only perspective however have no intuitive connection to workflow or task assignments. Where tasks are added under the "Workflow" tab they automatically execute if there is a Support Group/Technician pre-assigned to them. The technician (achieved from the "role" based security) view on the form shows the resource options and tasks at the bottom of the form. The Requester view only shows the resources - hence no intuitive connection to task assignment. Is it possible to present tasks in lieu of resource options so the Requester can select what they want executed from a list of options OR generate workflow (task assignments) based on resource selections?

Thanks, David.
