Editing a button within a CMS page to be different in each CMS page

I created a button link for two prototypes on one of my CMS page case studies - Lumen Loud. I go to another case study of mine - Friends of Animals, and am wanting to have one button, but can’t edit the button without it affecting the Lumen Loud case study. I tried creating combo classes, but I’m not sure if that’s the right approach. Is there a way to edit the button to reflect each individual case study differently?

Button in question…
