location scanning

I'm sorry if this has been asked before...when importing Radio Reference data from the library on the SD card to a TRX-1 using your location where are the imported frequencies stored? Are they in the preset scanlists, in the reserved scanlists, or in a scanlist that I have created? I'm asking...

Is there any way to program location alerts like dangerous crossings into the scanner using computer, without doing it manually. I could not find it in Freescan so does anyone have any advice?
