Save files in folders instead of separate files/customize pdf saving directory in TeXStudio

I use TeXStudio on Mac OS, and one thing I’ve always wanted to do is to save my files in folders instead of separate files. For now it saves stuff like this:

But I want to combine the files for one document into one single folder, so that I don’t have those auxiliary files flooding my finder. How can I save files such that the folder is created automatically with the files in them? Please note that I’m new to TeX, so I’m not familiar at all with macros and stuff. Thanks!
