I have enjoyed the convenience TM:PE has brought to me during these hundreds of hours of CS1 experience. A Big Thank You for every developer.

However, I want to know if it is possible to implement a lane-specific traffic light management. The reason behind this is that, while setting up a traffic signal for a left-turn-lanes-left-shifting junction before a CFI junction, I found it impossible to have the going straight and left-shifting traffic separated since all those lanes are categorized into straight traffic.
(I know having a separate road for the left-shifting lanes to actually make "left turn" for the shift would solve the problem. But, I do not wish to have the junction take way too much land.)

To make it visual, I the road layout before and after the junction are:
.|, '|`'|` .|,.|, '|`'|` '|`

.|, .|,.|, '|`'|` '|`'|` '|`

1 2 3 4 5 6 7 8

The problem is I cannot let lane 1 and lane 6-8 (going straight) have green light on when letting lane 2&3 have red light on or when letting lane 4&5 have red light on.

My thoughts for the solution is to have a lane-specific traffic light set-up functionality. Please help me know if it is possible to be implemented. Thanks a lot.
