Creating Subpatchers
A subpatcher is a good way to organize your work. It can hide messy details from the top level of your patcher or clarify the function of a group of objects.
Creating a subpatcher

When you save your main patch, the subpatcher is saved as part of the same document. If the subpatcher window is open when the document is saved, it will also be open the next time you open the main patch.
