Default [Q] Changing default email sort order

I have multiple email accounts that I read on my Note2. I prefer to sort them with unread emails on the top. When using the combined view I have to manually change the sort order. It will remember that until I click a notification to read an email. When I go back to the combined view I have to reset the sort order. Is there a control file I can edit to make "sort by read/unread" my default always?

Thanks,
Dave
