I can't prove it, but I always assume that various scanner software imports hidden data associated with the TRSs. Therefore, I always import the entire TRS, duplicate it, and rename the new TRS. Then, delete any unwanted TGs and Sites. Then I add the "dummy" site using the software, and leave it alone (Site 002, no frequencies). I've never tried to import a single Site. Also, the original imported complete TRS can be used repeatedly (duplicated/renamed) as desired. For my local TRS, I have one original imported, and seven dupe's, set up for use in different locations. Also, my best settings were 95 high, 15 low.
