Change default search location of Find Files

In Matlab 2012b I frequently use the 'find files' function. Every time I force it to look in the 'Entire MATLAB path' but the next time I open MATLAB, it forgets this setting and it suggests me to look only in the current folder.

It is of course not pleasant to change this every time, but above this it is sometimes very frustrating that something cannot be found, simply because the search did not include the path.

Therefore, I am looking for a way to change the default setting of 'find files' to search in the 'Entire MATLAB path'.

I read the help of the 'find files' tool, tried searching google and some websites, but have pretty much come up with nothing.
