Yes, this is the reason I havent upgraded mine to 5.3 yet. I am not to excited about this feature, so since it is here and will stay here I really would like for it to be improved a little. And that is exactly what I want,
being able to set the time frame per board.
Also, under the users preferences along with the different time frames to select (where it says "Default aged threads to be displayed:") there should be a "Boards Default Age", so that the different default age we set on these boards take effect if they have chosen "Boards Default Age".
