How to customise directions path rendering in OsmAnd?

OsmAnd+ 2.3.5 Is there a way of modifying the look of the directions path? There is too much going on there to my liking so I would like to: - remove the yellow arrows (not sure what they signify but they obscure the road names) - remove the black arrows (they are less intrusive but still obscure road names) - change the colour and transparency of the purple path
