Dear developers, please add the mechanic of adding the sketched out arrows (like hand drawn) over the map for the portal connections once you are going through them at least once, it will greatly contribute to the map navigation in the mid to late phases of the game and reduce the frustration of returning back to base by the roads which are frequently heavily dotted by the random bouncing anomalies.
This will also make map navigation much more fun and add more interest in following through the random portals
