Make my own Snippets

It would be helpful that if I create a section on a page with a bunch of content elements...and its perfect, that I can replicate that on another page easy peasy. I would suggest that there be an icon on the gray bar containing all the items that contain my designed layouts "create snippet". From there a window comes up for me to name this new snippet class. Now I can drag and drop snippets I have painstakingly created onto any page I choose without issue. Advance feature: If all snippets are the same, however I want to tweak one to be different..there should also be a "break snippet" that unfolds all of that into its editable state - as not every snippet will need to be identical..just saving me the work of having to recreate the entire section again exactly.
