In the config file for the Water Utility Profiling Tool, we are given the option to set a Point Layer (e.g. Manholes) to use to set the upstream and downstream ends of the profile graph. My stormwater network is comprised of several point types - catch basins, manholes, etc. Is it possible to choose multiple point layers to be considered by the Profiling tool, or should I do something to merge the layers prior to running the tool?
