Sometime you don't want Run To Here to start at step 1 of the current test. Instead you want it to start at some step of a parent test because the current test is actually a subtest. Currently this is not possible (starting from a parent test) which makes developing/debugging a subtest more difficult. Visual Studio has the concept of "set as startup project". If Test Studio implement something similar, a "set as start here point" it would make developing subtests easier.
