Edit Field of old submissions

Hello,

My form is https://form.jotform.me/63393478179471

Total submission are 207.

Just I have added one new field with name "Seat No."

Actually, I want to edit this field with numbers start from 1001 to 1207 for all 207 submissions.

Now I cant use Unique ID Widget for old submission.

I know EDIT option, but taking long time to edit for each submission.

So if possible please give me trick / idea to edit this field EASY. 

Thank you.

Unfortunately, there is no easy way to update them all. The only way is editing each submission at a time.
