Flights order

I'd like to request the Settings>Data Sort>Flights be split into three settings, please:

All (toggle)
Unsynced (toggle)
Synced (toggle)

Reason: I like to see my Unsynced flights with the upcoming date at the top with the dates increasing below it, but I want to see Synced flights with the most current recent date at the top and then descending to the oldest date.

Ex:
Unsynced
4/16/2016
4/17/2016
4/18/2016

Synced
4/12/2016
4/11/2016
4/10/2016

Thank you.
