Save Existing content without Overwrite

[IkelAtomig]

For example, I selected a portion of a paragraph in a page and I save it. Now, I select another paragraph from the same page. Instead of over-writing the existing content. How do I append it as extra data ?

It really depends on what kind of change you want to make. If you're just hoping to append to that note, you probably want to use the POST method, but you should look around at the online docs to see what options exist and which most closely aligns with your goals.
