How to reload JS script after making any changes in Google DevTools?

I'm new in Google DevTools, and I've got one question: 1) My test page has
got one JS script "func.js" with the following code:
$(function() {
console.log('123');
});
It works without any problems.
2) When I open DevTools in Chrome (Ctrl + Shift + I in Windows) DevTools
panel is coming 3) I open "Sources" -> "func.js" and JS console; it works,
I see "123" in console. 4) I do some changes. For example,
$(function() {
console.log('123');
console.log('456');
});
Is it possible to reload this updated code without saving in the original
file? I see no reload/refresh/remake buttons for this feature. I've got
the last Google Chrome version. Please, tell me, how can I do it? Is it
possible?
