Assume that someone has asked a question and some good answers have been posted. He wants to start a bounty and his reason is "One or more of the answers is exemplary and worthy of an additional bounty"
Can he offer two separate bounties at the same time? Or he should offer the second bounty 24 hours after awarding the first one?
Can he offer a bounty and then award it for two answers? I mean can he break the bounty in two parts when he wants to award it?
