How to identify which questions belong to the paid Practice Pack?

I purchased the CFA Level I Practice Pack, and I can see that each module says something like “Practice Pack Included (121 Questions).” However, I can’t find any indication inside the Learning Ecosystem showing which specific questions are part of the paid pack versus the free ones.

Is there a way to filter, tag, or visually identify the Practice Pack questions? Or are they mixed together with no distinction?

I want to make sure I’m actually using the paid content, but I can’t figure out where those questions start or how they’re labeled. Any guidance from people who already used the Practice Pack would be appreciated.
