How do I auto populate the contact field in New Incident based on who is logged in.

 Create an incident rule that sets the workitem_contact_id as the workitem_owner_id.

 You could also edit the sp_getdefaultworkitem stored procedure as well.

I am wanting to show more history in Comments.

When ticket is reassigned I want that date shown.

Also I want to show each Worker with the reassigned date.

This would show a complete history of assigned workers and assignment dates throughout the life of the service request.

Any suggestions or help out there?  :)
