Database with information you can refer to when making an article

In other tools it is often called "Snippet(s)". How it works is as follows: You can create a text file with information (for example about a company, like the services they provide etc.) Then when making a new blog article you can select wich "Snippet(s)" you want to pull data from. And now you can make a prompt like: Create a blogpost that explains the services of Company AB. This would create awesome personalized content.
