Motors - search more than one area at a time

I'm searching for a car, live in Wellington but happy to go to Hawke's Bay or Manawatu or Wairarapa or Whanganui. It would be great if I could tick all those different areas to search them all at once, rather than having to search each one separately. I can then sort all areas by price for comparisons, rather than having to write down or watchlist the likely suspects from each area to compare. So just being able to select more than one area at a time would be great. Ta.
