Changing ExpenseTemplate clears the previous Expense data loaded.

Hi Experts,

We have user expenses loaded through integration into Fusion Expense and we have two templates defined (Billable and Non Billable).
When user is changing an expense template in Oracle Fusion Cloud the expenses values gets cleared and users have to manually add the details again.
So how can we have the expense not cleared when changing hte template from billable to non billable.
