Missing ContactID on Quote and Order

We are attempting to keep our new CRM as Vanilla as possible.

But here is my issue:

When I create an Opportunity and specify an Account and a Contact, then I create a Quote, only the Account is copied over to the Quote.

I have looked at the fields available (assuming I was just missing the ContactId field) and all I can see is a text field.  Is there not a UniqueIdentier field for ContactId on a Quote and an Order.

I need this information to be carried across from the Opportunity.

We did find a table called ContactQuote which has the QuoteId and ContactId in, but it seems  to be disabled and the person I talked to at Microsoft said this is not working at this time.

So I have to ask, how does everyone else handle such a simple task?

Thanks
