Route with a Margin of Safety

[Algarve]

Is it possible to create the route with a margin of safety for the vessel is within the channel just like the picture alongside, but a plan for a route?

Forgive my bad English!

No this is not possible now.
One way to possibly handle this situation, would be to calculate a XTE , cross track error, and combine this with an alarm function similar to Pjotrs anchor watch.
