you can use a multi-form approach. Form 1, basic info & email (with confirm email). Copy/duplicate Form 1 so field numbers are same. Form 2 continue with questions.
In Form 1, create notification with link, that will auto fill completed field data intoForm 2
Note: dates & dollars: first form can use formatted field, second form needs text field. Such formatted fields do not accept the same formatted data.

You can set the first form to not send you notifications.
I use this in a cancellation / refund procedure. Customer completes the form, which sends link to the director who completes additional fields, generating update to customer and request to accounting with a link to provide refund details (customer & Director) all with webhooks that input in database.
