When creating the targeting of an experience, I can specify that the experience is triggered if SOME of the URL criterias are met AND SOME of the CSS / CODE criterias. It would be easier to include & exclude targeted URLs by having the possibility to also set that ALL of the URL criteria have to be met (URL AND URL). Same goes for CSS. This makes sense with the "URL contains ..." command, especially concerning subdomains / language parameters. This is currently possible via regex, but this is very uncomfortable, especially for "A/B Test Rookies".
