I have Traffic Global, and I just took a look at the global flight plans. I'm showing over 400 CRJ flights. On the top left, you can filter the list by aircraft by clicking the small funnel icon by the arrow next to the aircraft button. I suppose the amount of these aircraft that populate are based on the density you set in Traffic Global as well as the density you set in your simulator. You may do some tests by moving your aircraft to a location where that aircraft starts and make adjustments.
