Is it possible to advertise to 1 group only?
Let's take the next example:

I have 3 Groups (Noobz, VIP's, Admins)
Noobz has O as flag
VIP's has P as flag
Admins has Z as flag.
People who are not in these groups have no flags.

If i want to create a message which can only be seen by just VIP's i'd set the flags O and Z
But this way the people not in these groups gets the message too.

Another example:
I want to create a message only for people who are in Noobz i'd set the flags P and Z.
But this way Noobz and people who are not in the group gets the message too.

Another example:
I want to send a message to everyone not in these groups. I'd set the flags OPZ this works as it should.

How to make it so that my first two examples work?
