Formbuilder – Create new users in the admin area

Hello,

I just bought the Formbuilder addon and created a custom registration form for all levels.
However, these fields are not shown to me when creating users in the admin area / WP backend, but only when editing.
Actually, I bought the addon only for the reason to not have to make settings on another page after creating the member and to be able to complete the registration in one step.
Is there a way to display the custom fields directly during creation in the WP backend?
