Consolidate two submissions on connected forms

Hello,
I have created one form which has two separate parts (Part 1. the initial application. Part 2. further info which you can only fill in after your entry has been accepted). The questions for Part two are enabled by putting in a reference code at the top of the form which is given after acceptance.
My problem is that the replies therefore come as 2 separate submissions. How can I now consolidate those into one single form?

Hello miavr,

Thanks for reaching out to Jotform Support. We apologize for the inconvenience that you experienced. I checked your Jotform account tomw@salonpriveconcours.com and saw forms created. Can you share with us the URL of the involved form that has your concerns today? Here is your guide on where you can see form URLs. I just want to make sure, this is only one form with two parts or these are two forms connected?

You may also try to check the prefill from another form feature, please click on the links for the guide and details about the Jotform approvals.

Once we hear back from you, we'll be able to help you with this.
