Scenario : With the inability of resources and small end user group, We are planning on just having one template for service request. The approvals for the SR will be added once the it has been raised. At this point from the 'actions' we can set multiple stages of approval,which is fine and the way we want it. But once the stage 1 approver has approved his/her SR , the technician will have to go the sent to the second approver. Is there a way where the system will automatically send the next approver the email notification. 

Again this is when the approval stages are set from actions tab. 

Every SR will have unique approvers and we do not want our end users to have multiple templates.
