Schedule monthly "Community Reply" Blitz times (like Customer Support does with Cases)

Could we consider monthly Community blitzes where all we do is focus on keeping our replies current?   I'm trying to prepare for a couple of upcoming EBRs and finding posts from customers that have not been responded to in months -- but unfortunately many are product questions where I don't know the correct response.  It would be very helpful if we could catch up and use the Blitz time to ensure things don't fall through unanswered.  

Is there a way that Community admins can easily report on where we have response gaps?
