Renaming route and line names in a time slice without changing GUIDs

MasaoMatsuokaDev

We use the Line Network model in ArcGIS Pro 3.1.7 and ArcGIS Enterprise 11.1. We have also set up both route/line ID and route/line name fields. I understand there are two ways to rename these. One is to use the Rename Route tool. It renames route/line names across all time slices without changing route/line IDs. The second way is to use the Reassign tool. It renames route/line names in a time slice but it also generates new route/line IDs essentially creating a brand new route/line. What we need is a way to rename route/line names for a single time slice
