How to automatically compute room acoustics parameters from several measurements?

At the bottom part of Measurement->Measurement Tasks, there is a check box called Display selected room acoustics parameters. If this is turned on, then room acoustics parameters are being computed and displayed to a grid when measurement files are inserted using File->Insert in Active Group.... (If Room Ac. Parameters is selected as plot type, the selected parameter will be displayed in the plot as well. Note that this will reduce the speed, since the computation will be performed twice.) File->Insert in Active Group... will insert all marked measurement. To mark several measurements, hold the <Ctrl> key while clicking on the measurements that are to be inserted. <Shift> can also be used to mark a group of measurements.
