Is there a way to force a route across a break in the routable map?

Is there a way to force a walking/hiking route across a break in the routable map? 

I am using a routable openStreetMap in Basecamp and have found a few places where the roads, tracks and paths don't join up quite as they do in reality. Is there a way to force the route across the gap? If not I can switch to the "direct" routing type, but this means I lose the accurate distance information.
