Sadly the Rekordbox intelligent playlists are quite limited, you cannot for example set a "in playlist" condition. Me and other people have asked for, and been promised, improvements to their functionality since 2015 but well, nothing has happened.
However there are ways around the limitations, this is how I suggest you solve your problem. Use a field that is never, or hardly ever, used, in my case "composer" and use it as a variable. Use that to set your energy level, it could be as easy as "0" for Chill Techno and "1" for acid techno or something more elaborate to make it possible for more creative sorting. Now you make an intelligent playlist with the genre "Pressure" and composer "0" for Chill Techno.
