AutoTest: Show TestCases grouped into nodes based on executable name

I was wondering about the possibility of grouping tests by executable/target name. We are using CMake in a rather big project, and all our different libs' and apps' test folders are named "test" or "unittest". This makes it a pain to locate the relevant tests in the current possible grouping by folder name.

(The natural sorting can help somewhat, but it is not easy to select multiple test folders:
would it be possible to add a functionality to select several folders or tests in the tree at once, like holding shift/ctrl and clicking, rather than clicking each checkbox? I'm on 4.7.2 on Linux and I'm not able to do it.)
