It would be very handy, if when a document is generated out of Factory, a PDF copy of that document is saved somewhere in Factory (perhaps in the Collaborate area), to refer back to in future. This feature could be used for things like Purchase Orders, Quotes, Invoices etc. Something, un-changable, we can refer to, that is linked to the order, and easily accessible (rather than having to go into a separate email program to find it)
