Good news:  it's easy to do.

Bad news:  ...but not as a substack.

A substack of the stackfile that's been made into an executable won't be 
able to save changes because the OS prevents executables from modifying 
themselves.

So instead all you have to do is what every other app does:  keep any 
stacks that must be saved in a separate stack file.

Sarah Reichelt contributed this excellent tutorial on saving data in 
standalones to the LiveCode Journal site, which many have found very 
helpful for this:
