Writing in reverse chronological order

[hialemat]

Hi, I’m looking for a feature that allows me to write in reverse chronological order all the time.
I mainly use Sublime Text to write in markdown all of my notes, all along the day.
But on one file, which can be seen as my “daily log” or “journal/diary”, I write anything that pops up: phones calls, mails summary, dates, etc…
It would be great if I could write in this file in reverse chronological order. It’s my way of thinking/working, information stacks in this file, the newest piece of information being on top.
I know that I can use Edit --> Permute Lines --> Reverse, but this command is one shot. How can I manage it to have this “reverse command” active all the time?
Thanks in advance for the support.

do you just need a keybinding on Enter that will insert a line above instead of below?
and to reverse the clipboard lines on paste?

Yes, Indeed, the keybinding on Enter that will insert a line above should answer my need. But does the command “insert line” exist?
By the way, I don’t understand your comment regarding “reversing the clipboard lines on paste”

As easy as a “Cmd–Return (Mac) or Ctrl–Enter(Windows)” !!!
Thanks @kingkeith for your time
