Specified folders

[KonVas]

Hello, and apologies if that has been covered on another issue, or help guide. I was wondering if there is any way to keep the folders separate and be able to use just one folder per presentation. For example, I have material for two classes now and I would like to be able to separate them instead of having all appearing in my browser interconnected or not, I tried to create a folder inside my ~org-roam but it returned folder is read only in Emacs.
