Word Mail Merge - Varying Section Page Counts - Need to add blank pages as needed for duplex purposes

Hello -

I have a Word mail merge that gets data from an Access database.  When the records are merged, some records will generate 3 section pages, some section 4 pages, etc.  What I need is to add a blank page to the records that generate "Odd" section page counts.  The merged document gets duplexed (via a printer with duplexing capabilities).  I need to make sure that a page from one record does not duplex on to the back of other records when it prints.  Can this be done?  

Thanks.
