add "mark as read" icon on the default screen

Add ability to mark multiple emails as "mark as read" without clearing the selection.
To select multiple messages and mark them as read before deleting, one is required to reselect them all again for deletion. This is time consuming
Marking them as read prior to deletion helps to prevent the sender being filtered to junk in the future.
For example - 10 emails from a news forum with subjects I am not interested in does not mean I want the senders emails sent to junk in the future if I delete them unread, so therefore I am required to mark them as read prior to deletion.
There are many other reasons also for needing to mark multiple emails as read and then delete with a single selection.
Have a look at Gmail's functionality in this regard for an example of how to minimise clicks

On the main screen where we see all the emails, I'd like to select multiple emails and mark all of them as read at once.
