How to add "Reply to" field?

Is there any way to add a “Reply to” option in any account?
This feature is in every other e-mail client I’ve tried (Thunderbird, PMMail, Opera, EssentialPIM, etc.)

The “Alias” feature doesn’t seem to be what I am looking for, unless I’m mistaken.

I want to send from one e-mail address, the recipient will always see this, but the default “Reply-to” address may not be from me, I may choose to re-direct all replies to somebody else by default for example.

Any tips?

No, this is not possible at the moment.

Too bad.  This is a killer for me.  Oh well, back to T’bird.
