My wikis use the RandomSelection function to get a random character file on the main page. What I would like to know is if it is possible to adjust the RandomSelection function so that on specific dates only one specific character file is given out.

For example,
 * if it is August 6, then only character x's file is displayed,
 * if it is August 7 to 24, RandomSelection functions as normal,
 * if it is August 25, then only character y's file is displayed,
 * etc.

Would I have to combo up RandomSelection, the magic words CurrentMonth and CurrentDay, and #if or #switch? Is there a simpler solution? Or is this not possible?
