There is better way setting up the grid by getting DQ at qualy in correct order, admin write name of driver at chat and he goes wrong way from pits, when he gets penalty admin calls next driver1.) Prior to your race session run a qualy session in order to rig the grid. The best way is to get all drivers lined up prior to a timed lap in the desired grid order and travel around the timed lap at a steady pace as a procession. As each driver crosses the line to set a time, they call it out and the driver behind makes sure he goes over slightly slower. Takes about ten minutes and requires that your drivers don't mess about, cut track or otherwise compromise their time. Provided everyone knows what they have to do and use something like XD or other telemetry for the timing, comms is not essential to this process.
