Vocab Sets

I’ve had Lingq for a long time and have recently just started using it again. I’d like to start taking advantage of the SRS system but I only want to focus on vocab from lessons I’m currently doing (not from the 1200+ lings I created years ago). Is there anyway to create sets or to only do SRS for specific lessons/courses? And if not, can I just empty out my vocab list so I can start fresh?

Yes, if you go to the vocabulary tab and click the Filters button you can select by tag or by the name of a lesson.
