I currently have a bounty on a question; and an answer in mind that I would like to award it to. However, there's still a few days left on the bounty and I don't want to jump the gun and award it now, in case a better and more deserving answer shows up before time.
On the other hand, if I leave it too late and am otherwise occupied (read: sleeping) when the bounty expires, the system may not award it to anyone / award it to some other answer I feel is less deserving.
What I would like to do is set up a standing, revocable instruction to award the bounty at expiry to an answer of my choice. If a better answer shows up that I happen to review, I should be able to change my mind (switch standing instruction / manually award it); otherwise the system should carry out the standing instruction on expiry.
I'm sure other askers have faced a similar situation but have had to make a sub-optimal decision / the auto-award rules have not worked as they would have liked.
(Note: This is different from this question, which is more about informing the user about how the system would work if things ran their course.)
