Config File Per System

Is there any way to have a config file load automatically for a given system? I’m aware of the per core configuration, but what I’m actually looking for is a way to have a specific config to load for each system. I’m using the genesis_plus_gx_libretro.dll for more than one console, and the last used bezel from that core is loading to the next system. For example, I’ll get a Game Gear bezel for the Genesis.

Thanks in advance.

No, there is no system concept in RetroArch.
