The ability to curate custom quizzes by combining different exercises

Hi! Something that would be a GAME CHANGER for me is the ability to combine different exercises to make a personalized set. My school's practice questions are somewhat lacking so I'm trying to fill in the gaps and solidify what I'm learning here. But, going through each exercise individually is inconvenient and time consuming as I have to link them somewhere externally (like in google docs), then do one exercise at a time

Please upvote and comment if you like this idea. This feature would help me a ton

Thank you guys for all you do though, I and many others appreciate it :)
