How to separate the cover file made by cdr from the middle and divide it into two parts?

1. Draw two rectangles, and the size of each rectangle is equal to the size of a page.

2. Combine two rectangles: CTRL+L. Note that it is "combination" rather than welding.

3. Select the content to be edited, select the "Put into container: alt-c-w" tool, and put it into the prepared rectangle.

4. After placing, click the rectangle and select the combination: ctrl+K to get two pages.
