For my Analytics dashboards I want to be able to select all but one mailing type. I can filter on Mailing Type as seen in the screenshot, but I can't select which mailing types to include and which not.

On a specific campaign level I can select the specified emails I would like to include in statistics as a workaround, but on a higher level, I can't. But we use quite a lot of Mailing Types, and I want to exclude just one in my current specific questions.

It would really help me if I could select something such as Mailing type is NOT XXX for example. Or maybe check the boxes for mailing types to include, and leave the ones blank I would like to ignore.
