Text boxes and auto adding overflow boxes depending on amount of type.

I have a list of text set up in a singl text box which as a single line of text so it can be expanded seperately, the length of the list varies and it sometimes into the hundreds.

Is there a way to script and have the single line text box set up then automatically add the amount of new text boxes to fit the text in? In the same way as if I was to click the overflow button and create the next linked box multiple times?

or is the best solution to set up a template file with hundrends of linked single line boxes to cover the max amount the list might be?

Thanks in advance!
