i did read the manpage and i couldn't find that option. it's probably made intentionally hard to not ruin your config
i additionally, to this day, can't find solution for *.pkgsave files. that also seems deliberately disabled so you can't batch overwrite them this makes life hard like you or i who have own config management. altho, at that point, why not maximally separate config out. tho it could be more difficult and options to batch revert configs should be option so you have clean slate and can do own changes
