Hi Keleb,
usually, I solve such tasks with a small custom program, written in Java. The Java code will read the selected items (Test Sessions), and can copy them easily. The beauty with this approach would be to be able to make also specific corrections or additions, such as setting dedicated fields to special values (e.g. the state), or validating additional fields if they fulfill certain rules before copying them.
To code the Java program, you will need a developer with specific Integrity coding knowledge.
Hope this helps.
