can we pass additional attributes like location during the initial PunchOut request

the vendor wants the user's location information to be included in the initial PunchOutSetupRequest when the connection to the PunchOut site is first established. Their goal is to use this location data to automatically direct users to the appropriate site on their end.

The issue is that the location only gets transmitted later, not during the initial PunchOut launch from the supplier dropdown, which is what the vendor is expecting.
