Hi,

that's not (yet) supported. You can open a feature request if you want. 
This shouldn't be too complicated to implement. I already have some ideas...

This functionality is specified right now in ruta by using an additional 
boolean feature, which stores whether the original feature was set.

Best,

Peter
