No, as long as it is one of the prescribed actions (gold or cards). Scratching your butt does not count as an action I'm afraid.
The intention is to ensue that you have already made a call for your turn before you may be swayed by the subsequent pick of cards which could be duplicates or beneficial etc. Taking extra gold is rather more obvious.
Ok. Thanks for clarifying that. I also see now that scratching your butt simply isn't an option. It was likely to become a contentious issue.
