Create multiple posts using Post Data field?

Is it possible to use Post Data fields more than once in a registration or save to post form to create multiple posts of the same type? Or will it just overwrite the first instance?

On the site I’m creating, the registration process includes submitting 5 sets of race results; these need to be saved as 5 posts in a ‘race results’ CPT (already created).

There will also be a separate “submit race results” form for members to add more results later, hoping to offer bulk submissions instead of just one race per form.

Thanks in advance. I searched the forum and didn’t see any other questions about multiple post submissions.
