Cognos duplicate independent objects

Hello,
I was wondering how I can make two independent copies of objects (pages, charts, tables, etc.).
For example, when I copy my report page and change some properties on the second copy, the original copy also takes the changes, but I don’t want this to happen (changes in one copy takes affect in both copies, however I want them independent duplicates).
I searched google but couldn’t find any answers to this.
Thanks
