Feature Request: Studio folders or Tags for organization

I use notebookLM (i refuse to call it gemini notebook it's just not as good) for school revision.

My revision cycle goes sth like this for each week

- Create a Audio summary before my class so that i can listen it in my commute to class

- Create a text summary as source material for my cheatsheet

- Create video / infographic for my revision

And as you can imagine with at least 10wks of class materials, i have easily over 30 materials in my Studio. I would LOVE to have a folder organization feature or at least some tags i can attach to each source so that i can easily filter / reference the materials i am looking for.

Please please pleaseeeee consider these features. Thanks.
