Changing the magic number of an order?

[Forex Trader]

In order to select if a specific opened position should be managed manually or by an automatically trading expert advisor I'm differentiating automatically opened orders from the manually opened ones with their magic numbers. There are occasions when an EA's strategy goes wrong and it is safer to take the problematic positions out of the EA's hands. Of course, this should be done without suspending the EA's otherwise well going trading.
My question is there some way to change the magic number after an order was opened?
I see no reason why the magic numbers should not be changed afterwards though I could not find any means for changing them. It would be nice to see a function that takes a ticket number and the new magic number for the order of the given ticket number.
Looking forward to your answers.

No. It's impossible to modify magic number of an order.

You can only do it in code, not with a manually placed order
