Accessability Setting - Keyboard Filters - Bounce Keys

Hello all - hope you can help me understand if this is a standard KDE behaviour or not; F26 - Kernel 4.12.9-300. The Bounce Keys setting in KDE under Accessability Settings -> Keyboard filters only goes down to a minimum of 100 msec. I have a crappy keyboard with chatter on a couple of keys and have used the Gnome bounce keys setting to set it as low as 5 msec. That lets me use the keyboard for typing and gaming. I know this is from Xbouncekeys or whatever that utility is called, but I can't figure out how to set it outside of the DE or why KDE only lets me take it down to 100 msec. Any advice/thoughts is appreciated. Thanks, Zach
