Run shell command without deleting prompt

What variant of Codex are you using?

CLI

What feature would you like to see?

I frequently like to add context by editing the code and running !git diff

However, once I have started writing the prompt it becomes very cumbersome do run a shell command. You have to copy the prompt, delete it, run the bang command, then paste back the prompt.

Can we just run a ! bang command anytime, rather than only before writing the prompt?
