Ability for Expense Auditor to adjust conversion rate/amount increasing

Summary:

Hi,

When an employee submits an expense report with a certain conversion rate, the auditor is only able to correct the conversion rate by decreasing it but is not able to correct by increasing it.

e.g.:

In the Expense Auditor page, the Auditor realizes the rate and converted amount to be paid is wrong or not up to date and tries to correct the daily rate increasing it but receives the following error message:
You can't increase the reimbursable amount. (EXM-630408)
