Is it possible to use dosbox in a way that he loads the user's config file ~/.dosboxrc and also load a user defined secondary config file that will override what was set with the default config file ?

That would allow to have all platform specific configuration in the user's config file, and have a dosbox.conf file in each games/demos directory with settings specific to this game demos (eg : autoexec, sound card, cpu cycles)

Actually, it seems that when dosbox sees a dosbox.conf in the current mounted directory it will use that file, but won't load the user's default config first. And I'd like to have the later case. Is that possible ?
