need help re: mods with permission to edit usergroups

[found_nyc]

hello all...

i'd like specific usergroups, say super mods, to be able to move users between groups without giving them access to admincp. that's all fine, but "administrators" is one of the options that shows up in the list of usergroups they could potentially move people into. is there any way to limit which usergroups the super mods can move users between, or just simply hide the "administrators" option?

thanks for your help.
