SSAS: Clearing the MDX Script for a session in SSMS

Sometimes when troubleshooting performance issues you may want to comment out the MDX Script in your cube in order to quickly isolate whether the MDX Script is a significant contributor to the issue. So if you can reproduce your issue in your dev environment you can open up your project in BIDS / SSDT, comment out the script and re-deploy. But what happens if you can't reproduce the issue against dev. You may not have the same server specs, or the same data volumes or you may even have design changes in dev that have not yet been deployed that would cloud the issue.
