My "solution" for repeated endnote references

Hi team. 
I wanted to share what I do with documents using endnotes that want to have the same endnote referenced, using the same number, multiple times (sometimes many times) throughout a document. I couldn't find a good conversation about this in the forum and would love to hear others' solutions or thoughts on this one.

My team, among many other things, produce long documents in the health sector where various mentions of product benefits trigger inclusion of a disclaimer, for which we use endnotes.

Often, a product benefit is mentioned multiple times, sometimes many times, throughout a document.

To illustrate, we might have "wellness benefit" mentioned on page 2, with an automatic endnote linked to endnote #1. It's also mentioned on pages 3, 6, 9, and 16. Each time, the same #1 should appear. But then an edit comes in that adds a new endnote on page 1. "Wellness benefit" reference on page 2 would be updated automatically, but not the rest of them. Obviously this would cause headaches and slip ups trying to keep everything lined up, and puts the onus on the proofreader to mark up every # and keep track of the intended order of the endnotes.

My solution, while clunky, at least centralized things in a way that would leave no loose ends and takes the onus off of the reviewer:

I create a text variable for each disclaimer, named according to the benefit, set the value to the number of the endnote, and paste that in every subsequent mention of the benefit that should link to the disclaimer. I also create shared cross-references to bounce to the correct endnote for screen readers when needed. At the end I QC this by Finding every instance of superscript numbers and look for non-linked characters without the hidden-text variable box around them.

Obviously this is still slow on my end and a bit frustrating to work with (especially since while having the text variable modal open you can't work on anything else), and I'm looking into creating a UXP plugin that tracks each instance of the variable and lets you set their values quickly in a single window. Who knows when or if I'll get to that.

What do you think, world?
