So.. the core concept of *originate-coa* is just "proxy-the-coa"
instead of initiating a coa request?

Hmm..that is indeed an alternative, but like you said, it's kind of
not a neat way to achieve my goal.
And I'm worrying that might have some performance issue if supposed

What do you mean *after*? The next any-kind-of request?
But I really need they do it in the same sequence. It a bit upset

It's really impressive. Not a compliment at all. lol
