Can I put a try-catch in GUI initialization code?

I am building a GUI using GUIDE in 2016a which I will be compiling and deploying. I want to try to do some global error handling, and it occurs to me that any command given to the GUI first goes through the main initialization code before going to the specific Callback function. My thought was to put a try-catch block around the calls to gui_mainfcn. What's making me hesitate is that the code is bookended by some big old warnings:

    % Begin initialization code - DO NOT EDIT
    ... initialization code here ...
    % End initialization code - DO NOT EDIT

Could I break something by putting a try-catch block inside this initialization section? Is there a better way to attempt global error handling for a single GUI?

If you are looking to do global error handling, this may be an effective way. There could be some issues with catching errors from callbacks, as detailed in this post:
