Loading multiple images efficiently in Zoho Creator

I have an app in creator that is linked to a report template in Zoho Writer. One of the fields is a sub-form just for uploading images. Upon successful merge, the images uploaded through the sub-form will be arranged as a table with single column in the zoho writer output.

Normally, my process is to use the subform field, navigate to the folder with the required images, and upload the images one by one. If there are 10 images to be uploaded, the sub-form will end up having 10 rows

However, right now there are 600 images in my target folder that I have to upload one by one. I can't help but wonder if there is a more efficient way to do this. Is there any script I can use that will automatically upload all the images in the target folder and fill up the subform automatically?
