I am trying to create a heatmap of hiking routes. This will be a feature class, with each attribute being a different route. The hikers have highlighted on a paper map where they went. I am digitizing them by drawing a line of there route in arcgis pro. Many people hike the exact same route but I can not figure out how to copy a line I have already drawn and paste it into the feature class. At the bottom of the attribute table it says "click to add a new row" but nothing happens when I do that. I can copy a row I have already drawn but it will not let me paste it.
