Casting Defensively as Combat Action?

[MikeKn]

Is there a way to signal that a character is casting defensively (like the Fighting Defensively check box in Circumstances and Combat Actions)?

I'm looking for something to automatically apply concentration bonuses that apply only to defensive casting.

Similarly, is Spell Combat (Magus) supported anywhere (applying the -2 penalty when in use)?

I've not started exploring what I can do myself with the editor. I wanted to see if I missed something in main program, or if there is already a community addition which supports this.

Thanks!
