We don't have this feature at this team. Here are your options:
- Instruct the user to manually type the code into a field such as Comments or a custom field on the Order Form, and then apply a discount to the order after it has been received.
- Set up a pre-discounted presentation and generate a unique Access Code for that presentation (e.g. "TRADESHOW"). Then direct the user to your Showroom landing page where they can enter the Access Code to be redirected to that specific presentation.
If you would like to see this feature added in the future, please contact Support.
