Autocad text increment

Hello 

I don't know if what I'm looking for exists but to put it simply and so that everyone can understand: I'm working on the AutoCAD software and I'm looking for a way to optimize my time when drawing. To do this, I would like to know if there is a function that allows me to modify a dimension and a title on several files that are attached. To give an example, I am working on a large project, each part of this project is divided into several files and I would like that when we modify a title or a dimension on a subfile the modification is done on the large project. I don't know if that's understandable
