Accurately checking progress - help re-classifying my collections

I need help reorganizing my collections. It seems like there’s no way for me to do this for myself, so can you please do these tasks for me:

  1. Change all of my “known” clauses to “not known” AND “100% mastered”
  2. Change all of my “ignored” clauses to “100% mastered” (but NOT to “known”)

Of course, I do not want anything reset or deleted. I would greatly appreciate your help. Is this possible?
