Manually add copies of form submissions intoDB for very specific reson

Hi,
I've got a problem with extracting as CSV file all form submissions for a specific form. The problem arises because I was using the same form input field labels on multiple pages of that multipage form. E.g. there is a label "Firstname" on three of the 5 form page. This is accepted by ByForms, however, when exporting as CSV, the field content of equally labels fields overwrite each other in the CSV. We've got about 100 submissions already, unfortunately.

I absolutely need the data without anything beinf overwridden.

This is what I tried:

1. created a copy of the form
2. made all labes unique
3. submitted onof the ne forms
4. unloaded table "baforms_submissions" and inspected records for the original and the new form.
5. Made a copy of the 100+ records of the original form, and edited all labels and field numbers in the "messge" column of the DB records to match the single record submitted via new form.
6. Imported the new, edited DB records into table "baforms_submissions"

I do see the (imported) new submissions for the new form in the backend, so this basically seems to work

However, I seem to be missing one thing, because when exporting the new submissions via BAForms admins panel, all fields are empty.

I understand that this is a very unusual request, but can you give me a hint what data in the Joomla DB I'm missing to change? Must be something I'm overlooking.

I have exported the table baforms_submissions and then worked through the records for this very form. I have changed the labels in the "message" field of the DB records, e.g. "Firstname" to "Firstname 1", "Firstname 2",and "Firstname 3". This should fix the export overwrite.

However, after loding th
