Just wondering if there's any way to lock waypoints in MacENC, something like the the "lock" slider you see in iNavX when looking at a waypoint's info. I know you have to go through a couple of deliberate steps to change a waypoint in MacENC (and also reply "Yes" when prompted to save waypoints on quitting), but I wondering if there's any way to just make them uneditable. The GPX markup language doesn't have any kind of tag or something to define a waypoint/route/track as "locked," does it?

Thanks in advance for any help.
