Softcoding Content

Is there a way in wordpress to create a text file or section of content, say it is called “president” and have the information for the president in that file and then embed that content in any page that uses it? That way if the base file is changed the rest of the site is. This would be useful when for example, the president changes, it may become a bit challenging to change all the instances of the person on every page they are listed.

Any ideas or suggested plugins would be appreciated. Thank you
