Pen sensitivity with touch rejection

[ADS]

I recently downloaded and tried the beta version of Affinity Photo for Windows. Without sorting through all the menus, I was wondering if there was a way to disable finger input so that touch was only used for navigation while all artwork was done with a stylus (I use a Surface tablet).

Hello, 

 

Just purchased and started using Affinity Photo. I've searched everywhere and can not find an option to disable touch as input so I keep making lines all over my drawings. I saw a posting that said there should be a "Touch for Gestures Only" option in the tools preferences, but it is not there on my version of AP(which is current). I am using a SurfaceBook on Windows 10.
