Custom data with authcode / token

I have had an OAUTH server running using oath2orize for some time and use it with many different services.

I now have a need for a user to select a particular option when they perform the Allow through the Dialog. For example, when the perform allow they will select a particular option, 1, 2, 3 or 4.

I want to store this with the authcode in a seperate field as well as store it when the authcode exchange occurs.

Problem is that when I do the authsave in oauth2orize.grant.code() I do not have access to the req.query values passed in.

Any suggestions would be most appreciated.

Start at oauth2orize.grant.code() and the authsave callback, focusing on how req.query values are exposed during the authorization dialog and authcode exchange. Clarify the intended way to persist the selected option with the authcode and document or implement a complete flow that preserves it through token exchange.
