Hue shifter filter for Clasic Battlemap stamps

Love them. But if I want to make a map with a darker backdrop, I have to manually shift the contrast of stamps to turn from black to white and then bookmark those shifted stamps. Which also only gives me those options. Having some kind of filter or setting for all the classic battle map stamps allows me to shift all the classic battle map stamps at once, allowing me to make my map without worrying and adding an extra 30 seconds to every time I place a new stamp. Also, having it shift through hues allows me to create unique maps with deep red or deep blue stamps or other such changes.

This would allow us to change the "vibe" of these maps very easily and allow for more creativity without requiring as many stamps to accomplish the differences.
