[SE] Cutting Out technique

[sclose1970]

The prerequisites for the Cutting Out technique (SE pg81) list "any Per-based social interaction skill." AFAIK the only Per-based social interaction skills are Body Language and Detect Lies. Is this technique intended to be allowed for only those two skills, or could one learn it for other social interaction skills that have been floated to Per(i.e. a Per-based Diplomacy roll?)
