Is it possible to type a command in a the new pane but not execute it?

[Madd0g]

I have a bunch of tiny panes dedicated to single commands (like running tests), but I don't necessarily want them to run when creating the pane, just to be typed out and readily available in the new pane.

Is this possible somehow?

echo "rspec" maybe?

I need this feature!
Leave a command without running, so I go with enter to execute when I want.
Something like:

• commands:
  • wait: ls

result:
$ ls (but not execute, only prepare the stdin)
