In good old ArcMap, there was a "Flip Selected Lines' tool on the Water Utility Network Editing toolbar that flip all selected lines from the layer of your choice. It was utility-network-agnostic so you could flip all selected lines from any feature class.

Where is the equivalent feature in ArcGIS Pro? The ESRI instructions here don't work because "Reverse Direction" is grayed out. I can flip a single line using the Edit Vertices tool but I have many to flip.
Any ideas? Thanks.
