How to sign an .mlapp app packaged using MATLAB App designer?

Using Share to "Standalone Desktop App" in MATLAB App Designer, Is there a way to sign the installer .exe file that is generated, and also sign the application .exe file that is generated after the installation file is run? Currently, when using App Designer to package the app, it creates a build of the app and then packages it into an installation .exe file in the same workflow.

The issue I'm forseeing is that if I sign the installation .exe file, the application .exe file within will still be un-signed when it is generated after the installer is run. Am I right in thinking this? If so, is there a method of ensuring the application .exe file within is signed?

I don't believe it has the facility, but I'd suggest to submit this to Mathworks as an official support request/bug at <Product Support Page>. Of course, you could always just go ahead and compile a toy app and see if you install it locally.
