copying a TestSuite from one project to another

Hello,

I am trying to copy a TestSuite from one project to another.

In this particular TestSuite I refer to another TestSuite in my original project.
Before copying my TestSuite I copied the TestSuite I am referring to in my original project to my new project.
When I now try to copy the TestSuite I get a pop-up saying there are testcases missing. These are the testcases of the referred to TestSuite.

So even though the referred to TestSuite is in the new project the copied TestSuite doesn't identify it as the same as in my original TestSuite.

Is there a way I don't have to reset all my references?
