start a route in the middle

Good morning,

if i create a route from point a to point b and then to point a again (on the same road) but then i want to start the ride in the middle of the route, the edge 530 will alert me with "wrong way" messages or will it understand that i can ride in both directions (i can go to B poin in one direction or to start point A in the opposite direction) an so assume that i'm going to B point or to A point without alerts?

Thanks,

Roberto
