Hello cjcmetals -
Unfortunately it is not possible to specify a profile for use in a listing via a .CSV file.
You can add a profile to any Saved Listing, so you could upload a .CSV file with your title, description and price information and then add other profiles to the listing.
If you encounter any difficulties with this, please feel free to file a support case from under the Help tab of the site letting us know the specific issues you are running into and we will be happy to look into it further.
