Macro for pause area spells if get PK

[devilman]

Hi,

I've been doing some macro assignments around here, and now I need one... It is a very simple idea, but could be workful.

It would be as follows:
A macro that stops all area attacks if I catch PK, using only single targets until PK leaves, so, when PK leaves, I will use area attacks again.

Would it be possible?

I appreciate the attention.
