League Displays Suggestion!

Hello! I am a big fan of the League Displays application (I use the Mac version)! In particular one of my favorite sections is the "fan art" section. While the wallpapers and screensavers that have been provided in the application are amazing... I have the urge to add some of my own. I have a folder called "League Backgrounds" that I have been adding to since Season 3 and would really like to be able to add to the "League Displays" application. Is there currently a method to do this? If not, is it something that the developer(s) of "League Displays" is looking to implement?
