Preventing all PDQ updates until ready to work with them

This might seem a bit odd but here is my dilemma - PDQ is updating too frequently!  :)

Here is my routine:

- on the last friday of the month I :

     - manually update my WSUS server and push updates to a test group
     - push out any app updates via PDQ to a test group

- on the first friday of the month I:

     - push updates from WSUS to the rest of the network
     - push out any app updates via PDQ to the rest of the network
     - run reports in WSUS and PDQ to make sure everything is up to date

Sometimes though I won't get around to running those reports for a few days. Sometimes it will take me a few days to get through all the deployments.  And in the mean time PDQ is checking for updates - heck it has been checking for updates every day even since the first test round of updates.  i'm not complaining about this in itself.  I think it's awesome. 

But today on the 9th a new update came out for Thunderbird.  And while I've already pushed out the previous version of Thunderbird that was new at the time - PDQ is now showing that Thunderbird is out of date - I assume this is because the variable for Thunderbird's version has updated?  i do love that it does this - I just don't want it to be automatic.   :)

I figure I can create a rule in my firewall to block my PDQ server from the internet and just turn it on for a bit before I start on my end of month routine - but I wanted to ask if there was a way to do this in PDQ itself?  Plus i don't necessarily want to block the entire server from the internet.  Just PDQ itself. 

Maybe i could put a fake host in the proxy server?  Would that prevent PDQ from grabbing variable updates?  Then when I'm ready to check for updates on the last friday of the month I just temporarily switch back to using the host setting?  

Basically this is all because i want my reports to come out as clean as possible.  I hope this all makes sense?

thanks
