Location/Site Table for Node management

We currently have a distinct site code for each location that we have nodes. For reporting purposes and organization, each site has a single name, business group, analyst, etc. associated with it. We currently use the custom properties to indicate the described information.

Could it be possible to create a separate Site/Location table that could be updated through the web GUI to contain the unique sites and that site’s information? Rather than repeating the same information over and over in the custom properties, we could assign the sitecode custom property to the node and use the Site table in reporting. This would help maintain consistent data and minimize users creating inconsistent data.
