Give us the option to 'lock' expense attachments after a claim is approved, which would prevent an approver or finance staff member removing or editing the receipts attached to the claim once the expense claim is in approved status.

Currently it is possible to remove the attachments up until the claim is in 'processed for payment' status, which risks receipts which are needed for tax evidence from being lost and damages the integrity of the audit trail around expense approval.

If the above is not possible, consider adding a confirmation dialogue when a user presses 'remove' on an expenses attachment to reduce the chance that the receipt is removed in error.
