This is an idea I had as a means to replace the "Chart the B'tran Nebula" daily misison. This would be a daily patrol mission that would become available after a captain has completed all of the regular patrol missions. You contact Starfleet to accept this mission. Once you do, you are assigned to patrol a random sector block. One day you may patrol the Sirius Sector Block and the next, you might have to patrol the Zeta Andromedea. The point of the randomness is to break up the monotomy. Apon completion, you are awarded dilithium ore. This will also make those patrols more than a one time asset.
