Idea Summary
When copying pages across applications in the same workspace, most of the time mapping is incorrect and needs manual adjustment. I don't know how matching is currently done, but I think a simple comparison of the Template name could do a better job. Look at the following screenshot:
- Just two items have been matched correctly.
- Even built-in Templates failed to be matched. Some built-in are matched and some are not.
- Some custom Templates get matched (cl_Interactive_Report) and some don't get matched (cl_Standard_Page), although such Template exists in the target application.

Use Case
Sometimes the number of items might be a bigger and that initial matching (if done right) saves some time.
Preferred Solution (Optional)
Simple comparison of the Template name could do a better job.
