ability to ask or asign multiple parallel work inside a single chat session

What variant of Codex are you using?

CLI

What feature would you like to see?

When I am doing work in a session, I sometimes want it to do multiple things, or maybe when it's working, I want to ask a question.

And I want these things to happen simultaneously instantly.

Subagents can't be used here because they will need to be assigned by the main agent. (also idk if they get the whole chat context anyway)

So we want multiple main-agnets in a single chat
