Chuck,
Once you enter both the map and the lat/lon coords, you can use the import/export session to load/save both the map and coords simultaneously for future use. For my testing, I exported the session with map and coords before making any measurements, so I could quickly load a clean map on each startup.
In the case of mapping, the preset doesn’t store the map/coords, only the mapping session. So when you want to start up where you left off, load your exported session, and load a preset with the mapping settings you like.
Hope this helps!
Andrew
