"Great Canadian Railway Journeys"

It looks like the BBC has decided to change season 4 into two new series, the first one "Great Alaskan Railroad Journeys", and the second one "Great Canadian Railway Journeys".
It would probably be proper to split these episodes from "Great American Railroad Journeys" into their own shows.
Anyway to do this the easy way?
