Change Folio

Hi all,

in one of our processes the Folio gets filled with some significant information the requestor entered while filling out the InfoPath document.
Now I was asked if it is possible to add one more information to the Folio after the completion of the instance. This information is entered at the last set of the instance.

Can there occur any problems if I change the Folio or what would be a better solution?

Thx
