Need two Reports based on a Custom Field contexts but only when together

I have the custom field Channel Impacted as a Page and tried to Define a new calculated member that uses “Correspondent” and “Field Retail”. The problem is then I get issues that have just Correspondent or Field Retail by themselves as well. The Mgr only wants to see Issue that have both but not either or.

A second report, would show Issues that have No Channels selected yet or only Channels that DO NOT include Correspondent and/or Field Retail.
