So you are saying the requirement is to put a menu item in ribbon with 175 buttons in it - each with a different bit of text.

I presume the functionality you then want is for the user to put their cursor in a specific location in the document and then open that menu item and scroll down to see the word they want, then click on it to have that word appear where the cursor was on the page.

What is special about the words/buttons that it wouldn't be faster for the user to just type the word in their preferred location?

A simpler workflow since you have already created and populated a Content Control with the list would be to save that CC as a building block and then have the user insert that (one) building block in their required location and then click on that to see and choose the relevant 175 options.
