I'm wary of adding any conditions that are also actions. The reason is that it'd be easy to enter a vicious loop. Ie. you have action to put phone into PSM, and another rule with condition PSM that does something. Of course one could device some detection that such won't happen, but it's not necessarily that simple.

Anyway perhaps you can give a concrete use case, and that may either motivate me to do it or figure out a way to do it without these potential problems?
