Ability to reset analytics to prevent skewing or remove certain test data to confirm your setup works

If you are testing through any kind of registration, landing pages, etc. your tests show up within the analytics and will skew your data, namely your conversion information.

It would be great if there were some ability to run through either a. test flow like using the "Preview" option that doesn't track the data or b. the ability to reset or purge certain data (such as a recent experiment to test your flow that you have a customer go through).
