Hi @circlecube
I think you can do it by using two different methods, using Javascript code to add the rows or using PHP code to generate the layout dynamically.
Unfortunately, I believe using the Javascript code would be more complex than using the PHP code. If you want to learn about it, please take a look at this page: https://www.advancedcustomfields.com/resources/adding-custom-javascript-fields/.
If you use the PHP code, I think you can create several sets of custom fields and use it dynamically in the layouts. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/register-fields-via-php/.
I hope this helps 🙂
