Edit/remove payment statement when authors go to update a published dataset

Priority: Low
Affected: Authors, Helpdesk

A rare but not once-in-a-blue-moon inquiry that we get from authors who originally paid the DPC is whether they will be invoiced again when they version a published dataset because they see the statement at the bottom again. It would be helpful if the system could recognize that the dataset has already been paid for and remove that statement (unless they newly exceed the 50 GB threshold, which is very rare for versioned datasets), or if the statement can be modified for a versioned dataset to indicate that authors won't be re-invoiced.
