arrows...

i've searched around and found nothing about it..guess i must be the first to think about it...but in the case anybody knows already about it i'm gonna ask...is there the possibility to add diferent kinds of arrows to the game, im not refering to diferent efects of arrows but diferent visual aparencys of arrows...i replaced the old low res, low qualit arrows with new ones and they look like this...

but i wanted to add variety...like for example thre diferent arrows for arrow shoting units... any help?

I'm not sure, but I think you can change the type of missile a soldier fires in export_descr_unit

You can add new projectiles, but I can't remember off the top of my head if there is a limit to the number of projectile graphics...
