Link in Oracle Expense Approval Notification

So I want to customize the expense approval notification.

My problem is that I want to add detail to the expense section of the output, but the expense section of the output is created via the following link in the template; -

<?call@inlines:expenses?>

So my question is, "is there any way to add fields to the output that the call to inlines:expenses shows?" - the reason for the question is as there may be multiple expense lines whilst I can additional fields in a loop in the template, this will not be within the loop of the inlines:expenses, which would not be obvious for the user on (say) a ten expense line notification, where there would be two groups of 1-10 for the expense detail.
