[SCRIPT] Directional particle system

[Adrianis]

I want a situation where, to give the impression of wind blowing down a corridor towards a player, I'm using ps_dust_push.ps, which blows dust in a certain direction

However, when I spawn this with the create particle system function, its default direction means its blowing in a -X direction, when I need it coming toward the player on the +Z.

Does anyone know of an easier way to do this than making a custom PS every time its needed in a specific direction?
