Reach out to @Aaron_Boshers in support (assuming your a paying customer), have him help you with getting a Custom Host setup with the auto assignment tool. If configured correctly, you'll simply have a batch file you run that will install the host, set a personal password, and assign the host to your account. He helped me with it recently.
Incase you are out of the US. You might need to wait until wed as it is a holiday for many here in the States.
