The following script will set up an object style and paragraph style for the margin numbers (mimicking the format from your template) and will insert the numbers automatically (as an anchored object). If you want to update the appearance/position of the margin numbers, edit the paragraph style and/or object style.
The margin numbers will not automatically update when your pages shift; however, you can run the same script again and it will delete the existing margin numbers and insert new ones. Let me know if you run into any issues.
