[SUGGESTION] Ability to show only one cargo at station history with lines for individual destinations.

[geby]

Hi, when you got station where passengers (possibly any cargo tho) has more way to go, the station history graph becomes kind of useless, because it does not tell how many does want to go where... However, it could be fixed by adding individual destinations into drop-down menu, and let player choose them when they got only one cargo selected.
