Windows API SendNotifyMessage function

Allegro CL exposes many of the core Windows API window management
functions such as SendMessage and PostMessage, but missing at least in
Allegro CL 7 is SendNotifyMessage¹. Is this function exposed perhaps
under a different name?

SendNotifyMessage is useful for bypassing a Window's message queue (a
la SendMessage), but not having the sender block on the receiver's
processing of the message.

If this function is not available in Allegro CL 7, will it be
available in Allegro CL 8?
