Bulk downloading of Invoices

The current method of downloading invoices is laborious, clunky and very time consuming particularly if a provider has a large number of clients.. Can you amend it to something like:

When running invoices, ALL of them pop up in a list in a box with a checkbox beside their name – we then click the checkbox to mark which ones we wish to download and then the database downloads all of them at once as separate invoices. This would make this procedure much easier and quicker. Alternatively you could put a checkbox beside each invoice in the current listing which we could then check and a button to allow bulk downloading of individual invoices.
