Receiving approval from a higher moderator to moderate a post?

[Vonin]

Hello,

I'm sorry if this has been answered or there is already a mod for this, but here is my dilemma:

I'm creating a usergroup that will be for volunteer moderators. I don't want to give them outright moderating powers, but I was wondering if there's a setting where they moderate it like normal, but it doesn't go into effect unless a higher moderator approves it?

Thanks in advance.
