Here is a possibility: In the preamble of your main Notes.tex file, write

\def\INPUT#1{%
\immediate\write18{printf \jobname.tex > #1.texshop}%
\input{#1}}

Then, for your individual notes, use \INPUT{foo} instead of \input{foo}.
You will have to typeset from Notes.tex once, then afterwards the 
project root for foo is set, and you can typeset from foo.tex.

For this to work, your engine has to include the --shell_escape flag.
