Tickets are defined as 'Incidents' in the technician interface but defined as 'Requests' when shown in the self service portal?

Seems that any 'incident template' created that is set to 'show to requester' is identified as a 'Request' in the portal, even if it is technically an incident. With or without a service category 

I don't mind changing our workflows to fit what SDP allows but it so confusing!

So from a user (requester?) standpoint, when accessing through the portal I would prefer to see 4 things:

1. Service Catalog - Pre-set templates of common service requests

2. Generic request - Standard request template for uncommon requests

3. Incident catalog - Standard incidents templates with pre-filled information

4. Generic incident - A generic template for the user to fill out when it doesn't match a template

Is this the design that SDP allows? Seems that anything put into the portal is classed as a request, with no opportunity to show to the user as an incident?

Thanks guys!
