Joy, one more instance of the examples flouting the rules.If I might amend my previous comment, then:'To my knowledge, such an option is not explicitly included, nor even implicitly referenced, in any rules with regards to maneuvers.'
Why would it need to be explicit? Expanding targeting to a zone for 2 shifts is kind of a core rule.
No, it isn't.
I don't have much interest in playing "Yes it is." --> "No it isn't." so I'll just ask - why would you not keep consistent mechanics? Including targeting a zone for two shifts.
If you would care to present evidence for your 'core mechanic' claim, though, I would be quite willing to hear it out.
