Insert box with range

Insert box with range

I have created an insert box where the user can add additional information.
Unfortunately, there are a lot of insert boxes to be added so I had to create an add insert box button.
It works perfect, even remove insert box. Problem is, there might be cases where the user might add the exact same information 10 or more times and this might become irritating.
How can I make it with only one insert box which can repeat the exact same information 10 or more times? (the user has to select how many times to repeat the information).
