BATCH CDR to PDF conversion? Help!

Has there been any new features in CorelDraw that would allow batch conversion of CDR files to PDF files?

We are still looking at converting around 15k CDR files into PDF files and would like to also be able to embed fonts into the PDF file to avoid future missing font errors.

Most of our CDR files are fairly simple without any speciall effects like bitmap blurs, transparencies or anything like that.

We need to be able to open these files in Illustrator and not be presented with constant errors or incorrect colors etc....

Most, if not all of our CDR files are created using Pantone Spot Colors and some greyscale Black/White colors as well as Registration Mark color.

Is there a newer macro, working macro or new type of software that will consistently be able to do this? The older convert macros seem to crash or produce inconsistent results.
