For a database I'm creating I've had to put the custom clubs over the core coded clubs that already exist.

Is there a way that I can reset all of the logos to the editor-generated defaults, like the ones for the 19 EPL clubs that aren't Watford? I haven't tried anything yet as I don't want to ruin the system.

Also, if possible I would like to keep the national flags, just get rid of the club logos, kits and competition logos.

Thanks for the help.
