Hi Leesen,

Yes this is possible if the TCERs are not existing. So lets say you have a TestSuite with a testcase and no TCERs associated. You create a TSER and assign an owner. Run that TSER, the associated TCER created will have the same owner as TSER

Also under Manage Project Properties, in Execution Preference section you have an option "Automatically create test case execution records whenever a test suite execution record is created". Enable this and so whenever TSER is created,  TCER will get created automatically. You need not wait till you run the TestSuite
