Any way to add a subtitle to normal page titles, like the excerpt on blog posts?

Hi there,

I’m wondering if there’s any way to add a “.intro-text” below the “.entry-title” on regular pages? I basically want the same thing as the excerpts on blog post pages.

Here’s a screenshot of what I want, but on regular pages: https://photos.app.goo.gl/tbzyNR7CgjWkNCvf9
