Duplex printing-conditional page skip

I have a batch process that creates a report for multiple employees into a single .pdf. When users prints these reports in a dupliex printing mode, there are reports for new employee that starts at back of the prededing report, if the preceding report had odd number of pages. So I have a need to skip a page in this cases before I start writing the data for new employee.
Bursting by emplid is not an option in my case since the reports created are stored in a table and accessible via a link from a regular Peoplesoft PIA page. Users do not access these reports via Process scheduler or report manager.
