KMail Filter to Copy Attachment to File System

Hi Folks,

For my paperless office:

I have a number of accounts that email statements to me as Adobe pdf 
attachements.

I already filter to save these emails to an appropriate mail folder.

I'd also like to filter these emails to save the 'statement.pdf' attachement 
to my file system.

Is there a way to do this?

If not I'd like to request this feature. Can I do it here?

I look forward to any feedback or suggestions.

Thanks,
Peter.
