(I know I can do this by hand with 'merge layers' in the layers options but the amount of time it would take would not be cost effective)
I have a series of (67) PDF maps exported from ArcMap. I merged them into a single PDF. All of the maps have the same layers (e.g. fire departments, hospitals, imagery, etc...) but it lists those layers again and again for every page. Is there a script I can input (or batch process) that will merge layers from each page based on the layer name, so that instead of 67 hospital layers and 67 imagery layers, there will be just one of each?
