Assign Dates to Messages / Turn Messages into Calendar Events

It would be incredible to "assign dates" to messages that come into Front.

Similar to "snooze to this time", it would be better/best if there was a "due at this time" functionality. AND, if it could easily integrate with the calendar.

Similar and coming from the the opposite direction, it would be great to be able to "attach" a message to a calendar Event and/or assign the same tags we have for our messages to calendar events.

This seemingly simple but glaring gap with messages and calendars/dates, it is a big hole.

Otherwise, it is a KILLER tool.
