Postpond sending mail, and then insert additional info in hidden field

Hello,

I have CF7 integrated with Zoho, and after submitting i would like to pause sending and insert some text inside the hidden field, for example, hidden text field.

So this is how steps are going:

1. User insert data inside cf7.
2. after successfully insert all data, a popup will be shown (basic HTML, no connection with cf7 fields).
2.1. PAUSE/STOP cf7 functionality with sending email
3. With jQuery, i can register if the user clicked YES/NO on the popup that will be shown only if CF7 is filled completely.
4. Get clicked element and then filled hidden text field with for example YES/NO.
4.1. Insert data into DB and send an email.
5. All that should be inserted too inside Zoho Leads, but i think that will not be a problem if i can just manipulate with this hidden field.

So is there any way to do that, i am thinking about cf7 events, but nothing found that can solve my problem ??

Thank you so much!

Filip
