Allow both include and exclude patterns to be used at the same time

Currently we are unable to choose a combination of both thru the cli / UI.

Use Case

I'm being facing some scenarios where I would like to generate all *.csproj files except for *.UnitTest.csproj files , and currently I'm unable to do it, because I cant combine those patterns

In the implementation for the query_process the logic is almost ready to handle those differently, we just need a helper to allow it.
