WTH rerun step button in script/automation tracing

I want to have a button that reruns a step in a script using the tracing window.

You can run steps manually in the editor. But when you have a big script and you want to debug a script.

You might want to rerun a step if this step uses information from other steps and executes some self made code that contained a bug.

Then you can rerun the step untill fixed instead of running the whole script again.

This could easily be implemented and makes a lot of users happy.
