@smi-jonathan global moderators exist as a group to essentially be admins but without access to the ACP. If you want a restricted group of admins, that's what you're looking for. If you'd like them to be able to do more, then I'd suggest opening as issue on Github. As for your particular request, no, this isn't possible without a plugin.

@smi-jonathan This is something we'd like to support. Please open an issue on Github so we can track it more easily. Thanks
