Does anyone know if there's a way to search a large area at once? I am travelling across Canada and when I type in a city it only shows me the 250m and then I have to type in another city. It's hard and time consuming. Or if there's a way to see all jobs all over the country at once? Thank you!

No that is the best you can do. I can't get the entire province of Nova Scotia. I have a few monthly circuits and 1 of the stops is 6hr roundtrip rom the next closest location so I try to fill that one with a few extra stops
