An officer in the TOS era has been/is being promoted in both Rank and Role. They've just received a field promotion to Lt. Commander and are awaiting transfer to a different ship to become its Second Officer. (According to Memory Beta, this is the situation with Margaret "Madge" Alexander in The Star to Every Wandering.) While they are still finishing the last few days of their current assignment, how would you indicate the new role that "isn't quite active" yet? I've brainstormed things like the following:
- Second Officer Appointee
- Second Officer Candidate
- Second Officer Selectee
- Incoming Second Officer
- Pending Second Officer
- Presumptive Second Officer
