I'm either being incredibly stupid or I've misunderstood a "reusable" Gutenberg block.
If I make a block that I need to reuse then it is all very simple to save it and it's placed with the reusable library.
However, if I insert it back into the page and try and edit it then edits the entire block.
My point is that all I want to do is edit the text - not the layout.
What is it that I am doing wrong here?
