Using Cohort Definitions as base Cohort in Manage Data Exports (reportingcompatibility Module)

I need help on how to use saved Cohort Definitions as the base cohort of the data export while using Manage Data Exports . From the little research I have done, the data export form expects Cohort Definitions to be ReportObjects of type Patient Filter. However saved Cohort Definitions are saved as serialized objects in the DB. Does it mean we cant use saved cohort definitions in Data exports or does the module need some enhancements ??

Thanks !!!
