You can't change whether a charged light is horizontal or vertical once it's formed, but you can choose where it will shoot. The charge will shoot from whatever square is the last one in a string including a charged light. So you have some leeway to send shots where they'll count the most. This is pretty much the ONLY way to solve some of the harder cameo puzzles; time extenders are really helpful too.
