Who to restrict each user to submit only one ID Card (form)?

Hi There,

I have a question, regarding my front-end form (made with Meta Box – Custom Fields). This form creates automatically ID Cards.

So this form is only visible to logged users (conditional logic with Oxygen Builder), and with an account (Paid Memberships Pro plugin).

In each “My Account” page, logged users can manage them ID Card (see & update) - I have added an End Point with Meta Box Frontend Dashboard for post type with the attribute post_type (see here).

As they have access the form page, they can create another ID Card.
So, is there a way to restrict each user to submit only one ID Card, and still be able to manage and update from the dashboard them ID Card already created?

Thank you,
Eric
