Purchasing Features Request

Would it be possible to allow multiple contacts per vendor? At this point in time, we're forced to create a new vendor for every contact from a single company. It would be nice if, when we created a new purchase order, we could specify a default contact that would appear for the selected vendor -- but have the option, in a drop down box, of selecting another contact from the same vendor. Larger organizations could have multiple contacts at a vendor, and different employees within an organization may have different contact preferences.

Also, it would be great if there were some kind of conversation tracking for correspondence with a vendor, like the conversation history on service requests. If you're e-mailing a vendor from the E-mail the Vendor action in the Task List, it ought to be recorded. It's nice to have records, especially if multiple people are responsible for purchasing.
