Select active backends by drawing the shape of the trip on a map
This would only be possible if each backend was to provide a polygon for the territory information is delivered for. Now either by using the shape of the trip provided by the tickets imported into itinerary or by sketching out the trip on a map, all backend that intersect would be automatically activated an the rest of them deactivated. This should then reduce the amount of information send back and forward. Such a feature may also be shared with ktrip and make the search list of possible stations a much shorter one.
