Do I need both DirectRT and MediaLab?

If the interest in our research protocols using reaction time and DirectRT continues to grow I will be interested in what MediaLab can do for us. For instance, in the current study we’re having consumers take part in one product test via DirectRT and then, after they finish, I need to lean over the consumers to load the next input file for a different DirectRT task. I can't avoid this because I need to use the randomization functions (BGR, WGR) for each task and so I can not combine them into one. With MediaLab, I could randomize that order and eliminate the need to manually change the input files. Correct?
