Defaulting an Expense Report Template for a Particular Employee

Hello,

I have a requirement to Default an Expense Report Template created in payable to specific users.

The Business case is as follows:

HR Department has Multiple Job position and Grades. These Grades are from G1 to G9, G1 being the lowest.Now each grade has different Allowances and Rates for expenses incurred.

The Client requires that a person from the grade G1 cannot select and see the Expense Report Template of any other Grade.Currently the system allows to select all templates. I want when a particular user logs in the IExpense responsibility he or she can only select the Expense Report Template based on their Grade.
