Set page boundaries to object

Hi all,

This is probably a stupid question, but hopefully someone can help.

Is there a way to create a page from a selected object? For example, if I select a rectangle that forms the background of my image, can I create a page of the same size and in the same location? I used to use Inkscape, and it was very simple to do that.

I had to change my paper size and now my drawing does not align with the page. The drawing is very complex and I would rather not have to move it. If there is an easy way to realign the page, please let me know.

I hope that makes sense...I'm rather new to CorelDRAW.
