It's more fundamental than that.  If you're going to have multiple 
config files, you need some way of selecting between them.

This is something that has been discussed on this list before (usually 
in the context of pxelinux, but the problem as far as isolinux is 
concerned is identical); it is, however, something that isn't entirely 
trivial to do: currently syslinux relies on some variables being 
initialized at load time, and they would have to be reset before a new 
config file can be loaded.  That's mostly just a cleanup effort, but one 
that will take a bit of time to implement.
