Patrol multiple waypoints?

This is basically from the German base game. There, the Sentry and Guard commands were named Patrol and Guard (translated back). Naturally, when issueing the Patrol (Sentry) command, I was quite flummoxed why it didn't work as I thought it would.

So, why isn't there a Patrol command? Or at least the possiblity to add multiple waypoints to a ship? It would cut down micromanagement for scouting, for mining, you could have border patrols...
