Heading 1 Font / Single Post Title tweaking

Is it possible to have anything and everything that appears in this area (under the header before the blog post) to be in all caps? I’d rather not get into the habit of manually making all of my blog titles in caps just in case I want to change the layout in the future or it gets shared on social media / RSS.

I just want the titles to appear in all caps with the selected header font. There presently isn’t an option to do that for header 1 font.
