This has been a pain point in the past with clients. I'd be excited to see some sort of RegEx wizard where they can choose from a list of predefined / more common strings segments. I'd like to see this as an option that would pop up much like the email alert variables section or it could even equate to some out of the box RegEx definitions for users to choose from much like the format we see in out of the box SQL Alert trigger conditions that would be pretty nice. Empowering the user to not necessarily need to know the regex language to accomplish their complex config searches. This feature could be used in any modules that have RegEx Options.
