Setting an additional route via dhcp? Howto?

[Mr Gabriel]

I was wondering if it is possible to set route information via dhcp. I want some of my f10 boxes which download a stunning amount of stats data daily to use a separate ISP when accessing our public servers. 

Is there a way I can set this additional route using dhcp rather than having to manually configure all my boxen? (Boxen is my made up plural for boxes!)
