Hi @swshrey, happy new year and sorry for the time it took me to answer.
I think what you’re trying to do is definitely possible, you could use custom code in the header of your page to hide the blocks you want with a querySelector, and then use another snippet in the footer to toggle the visibility of the specific one you want to display back on.
For that last part, I would advise to have a look at Artur’s solution here, since mine above has been impacted by some changes in the meantime and might not be fully functional anymore (especially the “data-mappedto” attribute used in the selector).
Let me know if you manage to work your way around that, if not happy to help !
