Thank you!

OMG, you really have gone above and beyond for me. I will need some time to digest everything you've shared in the link.

Your assumption is correct: the only thing I want en dashes in is some number(s)hyphen some number(s)

No, I don't use backtick/tilde so no issue there. (I use the tilde sometimes in my Glossary Description).

Again, thank you so much! I will let you know how I make out. :)
