Add possibility to in an easy way work with the invoice suggestions page.
Approve / unapprove many lines at the same time. I.e. if you have 600 time reports splitted up over 20 tasks and dont want to invoice a specific task at this time. Now you need to untick and wait for loading line by line.
Close many lines at the same time. I.e. if invoicing is done and you want to close the remaining lines, or if an invoice is corrected the lines comes back waiting for invoicing again, although they are already invoiced, or some of them depending on the correction.
Makes it much easier for the project managers to manage their invoice suggestions.
