[OS X TeX] Per-folder project root

[Chris Goedde]

Is there a way to set a project root folder for an entire folder? I  
usually organize my lecture notes with a single tex file (Notes.tex)  
that inputs separate files for each lecture. It's a pain to make a  
separate project root file for each day's tex file. It would be great  
if there were a way to tell TeXShop to typeset any tex file in that  
directory using the same project root file.

(I actually do this now using a custom engine, but I think the above  
solution would be better.)
