TMS WebCORE: Add ShowDirections between two points in TwebGoogleMaps

I recently started to use TwebGoogleMaps and I miss very much a procedure to show directions between two points instead of two addresses. Currently is supported ShowDirections (Addr1, Addr2), but I have a case that there is no address (in the middle of a long empty road) and I would need something like ShowDirections(Lat1, Lon1, Lat2, Lon 2). Is this possible?

If yes, then you're the hero of the day.. :)
