A plugin that centrally controls text snippets, images, across multiple pages/wi

I’m not really sure what to call this so the subject is a bit wonky. ?? I’m looking for a plugin that would centrally control text snippets and images. An example would be on an author website you often promote your newest release via title and often cover image. An author might include the title in the header, in a spot on the home page and a spot in the sidebar of the blog. Likewise, they might include that cover in various places.

I’d love to see a plugin that let’s you input the text/image in one place in the backend and have it spread across various spots in the front end.

This is probably a bad explanation but something like that would save a lot of time. Does anyone know of anything like this? Or a better explanation? ?? Thanks!
