Question about the local store

[colwarg]

God bless you for storing the message store as individual plain text messages.

Now for the question:

I can create a program to scan the files and extract messages I want to store elsewhere for various reasons, is there a means by which when I do this, I can flag the message somehow to let Zimbra know "Hey, I've dealt with the message, please delete it from the local store and the server."?
