Is it possible in Outlook to define a Category based on
other Categories?

For example, I'd like to have a category for Contacts that
contains "Everyone except my business contacts."

If I have only three contact categories for example--
Family, Friends, and Business--I'd like to define a
category that excludes business contacts, i.e.,
automatically includes everyone who is Family or Friend
(or anyone else non-Business if I create more categories).

I could create a new "Non-Business" category by hand and
then assign it to everyone who wasn't a business contact,
but that's tedious and a waste of time. Allowing "boolean"
operators to define new categories is what I really want.

Is this possible in Outlook? Would one have to write code
to accomplish this?

Are there add-ins that allow this capability?

Any help is appreciated.

Thanks.
