That would in deed be cool and I'm sure it would be possible to set up something like that but it would take a lot of fiddling. One thing I will look in to when I have time (and other TW projects are finished) is Siniy-Kit's
description for how to use Google Sheets as a backend for TW. There are also
techniques to capture gmail messages in Google Sheets. So, combining these two should possibly enable what you ask for.... after hours and hours of fiddling ;-)
