How to apply effect on an instanc w/o affecting the same one

I read scirra blog post about using the same sprite to save memory and about using effects to avoid repetitiveness. The question is if I make several instances of a sprite, and apply an effect to it, for ex. burn, than the rest of the instances will get burned too. Is it possible to apply it only to one sprite.

Effects like that cannot be altered for each instance.

Well, you can enable/disable effects at runtime - sometimes useful.
