It's a basic thing and probably easily added in the code. But when you have multiple catalogs from multiple states its nearly impossible to figure out which catalog was used to create a pressure network in a model. Add the URL of the catalog to a pipe's, appurtenance or fitting's property as field that is populated with the data of the location of the pressure network. This would really help figure out which catalog was used to create that pressure pipe network. Currently we only see the pipe and structure/apprutenance/fitting data from within the catalog. We need to know which catalog that data is from as well.
