Medicine as both Firm and Insurance choices.

I've applied to medicine this cycle, with one of the unis I will get an unconditional to study medicine there if my application is successful.
If I were to get this offer and another medicine offer (which would be conditional) could I put it as my insurance?
Or are you not allowed to have an insurance med choice?

If you have an unconditional firm choice you can't have, or need, an insurance for any subject.

I meant could i put the unconditional as an insurance and conditional as a firm?
