TempoUp and TempoDown without physical keyboard

So I was excited to see that Kodi has added a feature to be able to speed up the tempo of a video. However, from what I am reading, the only way to do that is to use a physical keyboard. However, I am using an RPi with LibreElec and I just use the Kodi app on my phone to control it. Is there any way I can use the App to speed up and slow down the tempo? Or is there even a skin that has that functionality in there?

Any help would be greatly appreciated.
