Loading unique AEM grid CSS for a particular template?

I'm building a template that would benefit from different breakpoints from the rest of my site. I thought this would be easy since the breakpoints are defined in cq:responsive at the template level, but I'm realizing that I need to define the new grid CSS and I'm not sure how to do this on a template level without changing the grid everywhere.

Would anyone be able to offer suggestions or perhaps point me to some relevant documentation?
