Automatic match scanned documents on verificationsnumber

Please please please. Add the ability to send a scanned document to the scanning email so it can be automatically matched to a verification number. This would save hours of clicking around to attach documents to specific verifications and trying to find them among thousands of other verifications...

Something really simple like mentioning the verification number in the e-mail subject line like:

<VerificationNr:1234567> and e-conomic would automatically attach that number to the PDF. So all you have to do is login and click the button and it would attach the PDF to the verification.

This would save us HOURS!!!

And please don't suggest the API (if it is even possible), this solution is simple and elegant and easy to implement.... without creating a super complex system.
