combining multiple cdr files into one

I have 25 (small) one-page CDR files that would be easier to store and use as one file.

(Google finds only old and limited discussions on this topic)

Is there any way to combine these separate pages into one CDR file?    It  still would not be a very large file  (large files have been quoted to be a problem in some older posts)

Acrobat has a utility to combine multiple PDF's into one.    A similar tool would be helpful in this case.

Thanks   Richard
