SpriteManager 1 : Custom Material

Hello everybody. I just started Using SpriteManager 1 for a small project. I had trouble finding a tutorial, since SM2 is available, so it's possible my question is a beginner's.

I have created a shader allowing me to change the clothes color of an enemy.

I want that every time I create a new enemy, he has his own material with custom colors. But since the material is in the LinkedSpriteManager, it seems that I have to create a new LinkedSpriteManager for each material, which is way too expensive (I get 27 Draw Calls with 10 characters).

Since I'm not used to this plug-in, I can't find a solution.

As long as I'm here, I have some additional questions if you can answer them :

-If I have 10 different sprite sheets, do I really have to have 10 LinkedSpriteManagers ?

-Is there a way to mirror an image, so I don't have to have my sprite sheet twice ? Because at this moment, for each spritesheet, I have 2 linkedSpriteManager with a different winding : one CW, and one CCW.

Thanks a lot for your answers !
