Should the 24-hour timeout apply to bounties awarded for “exemplary answer”?

I set an incentive bounty on Is there a way to automate harvesting cobblestone? (before the new bounty system was announced). Once a qualifying answer had been posted, I clicked to start the bounty, and was confronted with the new bounty system. I selected that I'd like to reward an existing answer, but it's still making me wait 24 hours before I can award it!

For this specific bounty type, can the waiting period be waived?
