Dynamic custom page parametrized report in Termination page

can we create a embedded dynamic report in termination page in HCM based on page parameter "Termination Date" ? We need to apply a logic to find all element entries available with entry start date greater than termination date . The report data should refresh based on value passed in the termination date field in the page ? Is this feasible and if yes , what is the bind parameter name for termination date.
Example : pAssignmentNum will be page bind parameter in termination page for the custom report.
I am looking for such bind param name for termination date.
