Hey,
Please check out the following plugin:

It supports dynamic values. Also, you are to specify a list of ids.
I’ll create a demo with the doc soon.
For instance, if the element’s value contains the id, that means, that the element is visible on the page.
I’m using this plugin to speed up the pages.
For instance, the following page contains 4 repeating groups:

This plugin helps me to enable their source sequentially.
