renaming attachments when automatically saving to shared folder

When using the automatic attachments detachment/saving feature, i would like to be able to rename the file as it is being saved, and the new name should be something like "date received+custom text". I have some scheduled tasks that works on the saved attachments. i am not interested in renaming the attachments in the email itself, just saving them and giving them a name that shows when it arrived and who it was received from.

This feature would be really nice!

Thanks for a great tool.
