Choosing specific subfolders/decks of flashcards to study in one session

I like that you can go into a folder and study just the flashcards within it. However, it would be really useful to be able to select multiple folders or decks within a larger folder and study just them together in one session.

For example, I have a main Chemistry folder that contains subfolders for different topics, such as Covalent Bonding and Ionic Bonding.

When revising, I currently have to study each folder separately. I feel like it would be much more efficient if I could just select specific folders and study all their flashcards together in a single session.

Not sure how difficult this would be to implement, but I would love to see something like this in the future. Thank you for your time and for continuing to improve this platform. :)
