Hi,

For any given file I tried this with, after using the Import Manager Tool the 
file wouldn't compile.
What I did was for all Identifiers select as action "Create Import Statement". 
Then I selected for the whole import-tree the action "Use Single Named Import", 
When you finish it, the Import Management Tool also creates an import statement 
for the class(es) defined in that file:

import classX;
import classY;
import classZ:

class classY
{
}

And this results in a clash.
