Copy All Text Under a Heading/within a block with a button, command, hotkey

What I’m trying to do

Is there a way to select and/or copy the text underneath a given header with a hotkey? For example:

#H1

  • Blah
  • Blah

Say my cursor was in-line with the first blah above and then I click, say for example Alt + X and the command or hotkey allows me to copy the #H1 and the -blah -blah underneath it?

I don’t want to embed because I need to change the copied text and don’t want to alter the original. I also realize I could just cursor and select it all, but the size of the blocks would make that inefficient to do when I’m doing it hundreds of times a day.
