Make a copy of a model in repository

I'm trying to make a copy of a conceptual model (*.cdm) that resides in the repository, but there doesn't seem to be any way to do this. The model currently resides within one folder in the repository. My goal is to create a separate copy of this model in a different folder in that repository.

I have tried checking out and checking back in, but PD won't allow me to specify a different folder, name, or version during check-in. Can anyone help?
