Application Express Reporting Period is only 2 weeks by default. How can I report for more than 2 w

Within Application express, I need to do utilization reports and monitor activity that extends over 2 weeks.  It appears the wwv_flow_activity_log2$ table is setup to automatically remove data that is over two weeks.  So if I try to run a report for a month, it only reports data from the past 2 weeks.  Does anyone know if there is an oracle approved way to extend this 2 week period to a month or more? 

As an option I can create another table which contains all the data but this does not allow me to use the oracle apex reports that are setup within the workspace.
