Additional subheading tag only for one cms item

Hi there,
I would like to know, is it possible to add a subheading tag(h2)only for one cms collection item without it affecting other designs items in the same cms collection.

As you can see in the above image, I would like to add the subheading only in one cms(blog) item. I know it could be possible making a static page, but I might have to add more in the future in some items. in that case, it would be troublesome making static pages instead of cms collection.

so if anyone knows, how to solve this,
any advice would be helpful. thank you

You could use a CMS text field for subheading then use conditional visibility to display it when present in your CMS template.
