I've created a strip index page for my map series in ArcGIS Pro using the Generate Rectangles Along Lines tool. My problem is that the horizontal labels do not rotate with the map frame on the layout. The labels always point towards the north, even though the north is not directed towards the top of the layout. Is there a way to fix this?
Edit: I added an image to clarify the situation. On the layouts (shaped like the blocks) the blue line is horizontal, which is what I want. However, I want the labels to be displayed in the same direction.
