Application Deployment Type Detection Rule if Registry Key does NOT exist

I'm wanting to deploy an application in SCCM to machines in which a particular registry key does NOT exist. By default, "This registry setting must exist on the target system to indicate presence of this application" but I don't have any other available options because I am not looking for any particular value of the key.

Basically, I'm in search of a way to set it to "This registry setting mustNOT exist on the target system to indicate presence of this application.

Any suggestions?
