sharing test cases between projects

Test Cases can be shared between projects in Zephyr Scale.

eg: Project A has 10 Test cases and if you would like to reuse 5 test cases from this project in Project B, then navigate to the create new Test cycle section of ProjectB, then click on Test cases > add test cases > in the add existing Test case popup select the project that you would like to the test cases to be shared (in this case Project A) and select the test cases you would like to reuse and click Add.

Remember though if you change the content of the test cases in Project B, the changes will be reflected in the relevant test cases in Project A as well. 

Is there a way we can copy test cases between projects (and be able to modify the test cases to suit that project without effecting the integrity of the original test case).
