I was wondering if someone could point me in the direction of how to swap the model for creatures, i.e. to make a mud crab look like a dog. I was able to this for FO3/NV/Skyrim with the Template Data section of a creature's page in the GECK/Creation Kit.

However, I don't see such an option in the TES Construction Set.

Any help that can be provided would be terrific.
