How to manage manual test scripts and test scripts which are automated by an external tool

In our workflow we first develop and execute manual tests for new features of our software. Therefore we define according test cases and manual test scripts. If the new features are stable we start to automate the manual tests with the eclipse based tool Q7. To separate the manual and the already automated I already have seen that you can use a self-defined Category.
My question is: how can I prevent that the already automated tests are listed in a related test suite execution record. Here I only want to see the test cases which are still manual and have to be executed by the tester.
