NOT operator for logical condition

[moxplod]

Details

The use case is that I have in instances some advanced logic in filters. And I want to create an inverse filter and a list of records from that.

It would be great to have a NOT operator that can be applied.

Example filter that a user of mine created:

Company.NumberOfEmployees>=50,(Title=*Manager|Title=*Director|Title=*VP|Title=*President|Title=*Chief|Title=*CEO|Title=*CFO|Title=*COO|Title=*Head)

Now they also wanted to create an inverse list to see what was filtered out easily.
