Transform app.config with Xamarin

is there a way to apply transformations to the app.config file in Xamarin?

Basically I have a few tests that will run on Visual Studio and Xamarin. On Visual Studio I transform the app.config values using SlowCheetah, so I don't have to change them every time.

When I open the same project on Xamarin, it only reads the main app.config even having the Configurations for the others there. I believe slow cheetah is not compatible, but is there any other file transformation that can be used on Xamarin?

Thanks!
