Depending on how you organize your TF there is a way to do it. when you click on a jump point there is a command to detach non survey ships. If the jump ship is not a survey ship then do that, have the next order be to transit the jump point and divide the fleet. If your default orders are set to survey the system (keep grav and geo surveyors seperate) then the sub fleets will automatically start to survey the system. It is usually best to use the survey multiple points command as this will let you jump through time faster, and have your fleet more efficiently survey the whole system. Each ship knows what is already marked to be surveyed by the other ships in system.
