Why can't users with SDAdmin roles edit change requests?

We're using SDP 9006. I'm in an SDAdmin role and need to make a change to a change request. Unless I've been added to one of the Change Roles in the actual request, as an outsider (but a SDP admin), I'm not able to make changes to a request. Is this by design or do we have something configured incorrectly? Thanks!
