Is there any way to remove roads from territory that is either yours or neutral?

Part of the reason for this is my mild OCD and the urge to make the road links between my cities aesthetically pleasing.  The other part is to create buffer zones in neutral lands so enemy armies take longer to get to my territory.  This didn't really become an issue until I researched the tech that automatically builds roads between all your cities AND started capturing enemy cities.  As soon as I capture an enemy city, a road links up to the rest of my empire regardless whether I want to keep the city or raze it right off the bat.  I raze most of the AI cities I capture because they tend to be built in suboptimal locations but this leaves roads leading back into the heart of my empire.  As I retreat I'd like to have the option to remove some of the roadwork so enemy troops can't follow me too quickly.  Also, I've often wanted to cut off enemy cities from the direction that likely reinforcements are to arrive from.

So, is there any way to do this in the game?  My pioneers don't seem to have the option, and neither do my Mancer units with the "road building" trait.  Also, there's no drop down option like "Raze" when my units are on a road.

Anybody have similar compulsions and figured out how to do this?
