I make several expenses, all paid by eployee, and report them together. When I register payment less then the total amount, the report is straight labelled as 'paid', although there is still amount to pay the employee. There is no button 'Register Payment' anymore unlike when I post and register payment for a report of a single expense. 

In the Invoicing module, the amount is still preserved and I can do a manual journal entry. However, I find it a mistake for the report to be labeld as 'paid' and the Expense module becomes less functional since I'm going to rely on the Invoicing module to continue the job.
