Reverting to Default Tab Caption

[cfenn]

When I run scripts, I want to append the script title to the tab caption, and then remove it when I'm done. By default, the tab caption is dynamic, meaning that it follows the prompts in bold. However, after I change the caption once the script starts, the tab caption becomes static. Is there any way to revert the tab caption to its original, dynamic state once the script finishes other than restarting the session?
