Detecting when a player can't see his own unit

[Xonok]

I'm wondering if this is possible.
I can survive without it, but it would make one of my ideas a lot neater in implementation.

How can a player not see his own unit? If it has 0 sight range.

It's in the boolean condition part. I think it's near the bottom of the boolean options
