Wondering how to add to a master kml file or something like that, so that I can keep an up to date list of access points.

Right now, I don't understand or see a way to do this.

I can only stop and start a session, which I have to name each time.

Am I missing something, or is this not a feature/possible?

I really want to:

Go to eat at one place, walk around the building and have one capture file (burger kind, for example). Then be able to add that to a master kml file of verified access points (for example, deciding which one is actually at burger king (should be the strongest signal or in the middle of where I walked around) and adding it and ONLY it to the file.
