test cases tree

[Tim (PassMark)]

You will need to create a sub test suite and store and sub test cases in the sub test suite, the sub test suite can have the same name as a test case already in the test suite.

i create a test case (1.0)
but found it that i can't do a sub test cases under 1.0, exp: 1.11,1.12
is there any setting to make it well orgarnise as a tree of main test cases.
then i can add on 2.0 with 2.11,2.12....so on
thanks
