Clara 2E Customising screen touches using Plato?

[GDevine]

I've been using KOReader for a year or so and really enjoyed that I could touch the top of the screen to turn the page as it works well with my bluetooth page turner when I'm laying down to read.
When KOReader stopped working after an update recently I decided to try Plato instead, and the speed difference when changing pages is incredible.

My only problem with Plato is that I can't see a way to change the touch settings, which means my page turner doesn't work unless it's hanging off the bottom of the reader.

Is there a way to set Plato so that touching the top of the screen (or even the left side?) will move the page forward?
Or maybe to have my book progress sync between KOReader and Plato, so I can use KOReader at night but Plato during the day for the better refresh rate?
