Use of flags during testing

Are there plans to implement testing levels (when pressing RUN) with flags? Currently, the only way to see if your code involving flags works is to SUBMIT the code. This becomes a problem if you are trying to complete one of the repeatable, submit-once-per-day levels if you have some minor error or you’d like to enhance your flag-related code.

When you press run, the flags from your last submission will be there, which about as good as I’ve been able to figure out how to do it.
