Right to left option for footprint histogram

Hello, I would like to suggest an easy way to improve your footprint or cluster chart. I always use two footprint, both with a histogram and imo it would be easier to set one of the histograms from right to left. Currently they are both left to right and I would like to see the left one right to left and the right one left to right. Hard to describe, I hope you will understand. Thanks in advance!!
