How to have multiple rez at once?

I'm currently downloading some mods and skins, but it will only let me enter 1 -rez command at a time, any way to have multiple rez commands?

I think youre best bet would be to look for a mod manager (I may be totaly off as I dont mod AvP) But hope I helped

Spot on m8 :).

Heres the mod manager link for future reference :P
