Hello dear,
The 99 EAs are separate, and they need to be traded on separate charts. However, you can always import them back in EA Studio and export them as Portfolio EAs.
It is totally a different method. As you know, when we trade many EAs separately, we can follow their performance on Demo and put on live the ones that trade the best.
And if you have them in a portfolio, you need to go straight to live and remove those that lose. So adding them as a portfolio to the course would not make sense with the course content.
Cheers,
