I am using MapPoint @k@ for trip lanning for a motorcycle club.

How can I tell Map point that I need to stop every X ( +/- y miles) miles at a gas station (preferred station maybe) for fuel and say 30 minutes? The gas stop should be no further tahn Z miles from primary route.

Things like that. Also similar for points of interest on long trips, and such. I am new to using this tool, and woudl appreciate your input.
