Just like how in custom senario we can click on a bonus and apply units to each tile in that bonus, we should also be able to click on the bonus and change the number of units that bonus provides. This could streamline map creating and provide a much easier way for game creator to specifically tinker with their games. This would also provide a much more appealing look to people who want to creat games but are intimidated by the current system we have of changing bonuses.
