Summary: I would like to specify an engine mode e.g. "Run db tests locally, all other distributed".
Details: I would like to define grid nodes condition in the NCrunch engine mode settings. A first simple step would be to add setting similar to "Tests to execute on this machine", but under the Distributed Processing node. This way I can ensure no test with category [DbTest] is executed on grid nodes, but only on local (where I have the test db set up).
