Is it possible to block-compose a document in Google Docs?

Question

Google

There are many documents in a particular folder. I would like to make a large document that would consist of the rest. Yes, so that when a document changes, the large one also changes. It is also desirable and vice versa, when changing a large document, the changed children also changed.
It seems that I have not heard of such a thing, but what if there is such a thing?
