Quote Order Wizard Customization & EpiBinding on OrderHed

I’m trying to customize the Quote Order Wizard form by adding two new controls and binding them to two UD fields. The two UD fields that we created on the OrderHed table show up in the EpiBinding list for the SO Entry form, but they do not show up in the same list for the Quote Order Wizard form, even though OrderHed is in the list. Has anyone had fields show in one form’s EpiBinding list and not in another? I’ve tried to research this but have found nothing. Thanks for your time and any insight you can provide!
