Process Type Action to Resolve Incident

I'm working on a workflow that will be available as a Process Type Action for Incident Management.

I'd like to include a button to resolve the incident right from that form.  The form would have a Close Code and Resolution notes fields and could do some validation.

I know at this point the Incident would be part-way through the SD.IncidentManagementSimple.  Ideally I'd like to automatically progress it through the Resolved path and do all the normal things like manage SLAs, trigger rulesets etc.

What is the best way to do this?
