Best way is to copy & paste within the .ini file. But these positions are fixed (i.e. they don't translate from gate to gate).
Umberto, it would be really nice to be able to apply a translate to pax waypoints, parking guidance, baggage carts, pushback tug, etc. I'm doing the gates for LTFM (Scenery TR Design) and it's about 500 SHIFT+ARROW clicks to get each VDGS position in place (my fingers, and keyboard, would very much appreciate this!)...
