[REQUEST] Show transportation lines on collection map

[Rinma]

Is your feature request related to a problem? Please describe.
It would be nice to see on the map of a collection which transportation is used and from which destination to which.

Describe the solution you'd like
A colored line from the start of transportation to its goal. Make the line colored coded to the type of transportation used, and/or show a small icon, based on the type, on the line.
