In Tray: Ability to match to a Purchase Quote

[Valna]

It would be very useful to be able to upload quotes for purchases so we can then check next to invoice once received.

It would also be helpful if we could see invoice by hovering over &  printing the invoice once attached to a purchase.

It would be handy to be able to attach a document (e.g. engineers drawing in pdf) to a Purchase Order or Purchase Quote.

Agree it would be ideal if could attach surporting documents to tax invoice.
