Is possible to auto update the slug when publish the post?

Hello, i have this problem:

For example:
John Smith posts a draft on WP.
John Smith calls this draft “My Writing 2”
The post slug automatically changes to “my-writing-2”
A few weeks later, John Smith finished writing the draft and changes the TITLE.
John Smith presses “Publish”.
The slug does not change when the title changes.
Now, John Smith has to go back and manually change the slug.
John Smith wants the slug to change when the title changes.

I am usin PHPmyvideoblog plugin, so there are automatically creted drafts with old title. Now i need to change title and publish the post. But the slug is from the old title. I know, i can change the slug manual, but I need auto updating slug when publish.

Is some plugin to fix this?

Thanks for help and sorry for my bad english ??
