Fall of the Samurai skirmishers

[Elianus]

Let me begin by saying that my modding skills are at the moment limited to stats changing (well, some of them at least) so forgive my ''noobness'' . OK, here goes. I was very dissapointed to see that only the first rank of skirmisher units fires (and standing no less) so I am trying to see if I can make them behave like proper light infantry. Someone made a mod that gave them light infantry behavior but the units would take a lot of time forming up before they could open fire and they would all shoot timed volleys. Doe anyone know what stats I should modify to make them behave like true light infantry?
What I want is basically this:
1. Make them open fire immediately without the need to form up.
2. Make them pick their targets and not fire like a 18th century line infantry unit.

I tried changing the spacing but it did not work. I know that both of the above should be possible because the ashigaru sharpshooters of TROM3 work very well but I can't seem to find what I need to change. Thanks in advance.
