How to automatically select same region to scrape in OCR text

I need help finding a way to automatically have the Get OCR Text activity select the same regions of the PDF file without me manually clicking on the indicate screen button.

I have tried getting the data such as the coordinates of where I would usually will be selecting and inserting it into the Get OCR Text activity properties but I get an error message, it looks like the user has to manually indicate on the screen the region to scrape.

Does anyone know how I can achieve this?
