Ability to edit item vendor or link within the Quote, Invoice or PO.

When we create an Quote for client (I think all the work and corrections need to begin here so that the items carry over exactly as intended to invoice and then PO), that under each item on that quote where it says "view website" that we can actually change the link and/or vendor directly specific to that project? This way we won't have confusing information re: manufacturer, vendor, random website, duplicate vendors, etc.
