Traffic Shaping - Manual Config

[carbeam]

Any one that could answer this would be great, is there a way that i could turn off traffic shaping and start up pf using a script on load?  What i'm looking for is configuring pf manually on a pfsense box so that it works properly with multi lan.  I understand that the web ui does not support more than 2 IF but if could just manually configure i would be fine with that just need a kick in the proper direction.
