Active Duty Resident

Been wondering about this for a while now so finally asking. I'm an active duty Marine and a Indiana resident so I know i'm license exempt (when i'm on leave) however I've always bought myself a resident license since I can't always take leave to hunt (just don't have that many days to burn). My question is, can I register to have two CID's? I ask because when registering my harvest with the online system, I have to enter my CID (which I have because I have a resident license) BUT if i choose the option to provide me a CID because I'm in an exempt status, I have then will have to enter my name, address, DOB, etc. (the same information which is already associated with my resident license). So if i registered for an except license CID, will the system accept the same info being entered twice for an individual? I have not attempted to go in to the system and register for a "exempt CID" because I don't want to dork up my already registered info.

I've yet to need a bonus antlerless tag BUT if i'm allowed to have two CID's because of my particular situation, then when i do harvest something while on leave (such as today when i was lucky enough to bag a doe) i would have registered it using my exempt CID vise my Bundle tag.

Thanks.
