Prevent auto reconciliation method for specific period

Summary:

Can you prevent the Auto Reconciliation Method from closing a recon for one specific period?

I know if you are doing autorec using rules you can use custom attributes to prevent the rec from closing. What we would like to do is to set the Auto Rec Method for some profiles to be "No activity" and let the recons close for every period except Oct. From what I have read and tested the rec seem to close before any rules are run so there doesn't seem to be a way to get this work with the built in Auto Rec Method.
