Dell Command Update - Custom Catalogs

I'm new to managing Dell Command Update in our environment. I've found documentation for DCU and figured out how to deploy it with settings. One of my goals is to create a static Point-in-time list of tested updates to include in our environment. Documentation indicates I should do this with a custom catalog. After being pointed in multiple directions to do this I was able to create custom catalogs for one of our Latitude models. I now have an option to use a "Hosted URL" or to download the custom catalog. I would like to deploy a list of drivers to each of our workstations and have them download those specific drivers from Dell instead of hold the driver files locally. Is this possible? Can I simply direct Dell Command Update to the Hosted URL? How do I use a Hosted URL with DCU? I don't see much in the way of documentation on the Hosted URL option.
