BFEditor, how to create a clone of a vehicle?

Hey guys,

I recorded a vehicle, have the files ready and I want to test it, putting the sounds into an existing vehicle. But I don't want to "break" the vehicle in case I screw up. Is there a way to create a clone of a vehicle? Is it enough to just copy the folder?

Thanks! :)

EDIT: Okay, copying does not work because BFeditor thinks the humvee is there 2 times and gives errors about too many networkable objects.
I'll try something else.

EDIT:

Hah, funny shit! Went to record my buddy's car today and put the sounds into the game as a test. Damn, not smooth but it's fun! :D Still I wonder how to create clones. :-/
