Story Engine alert sound for when prose is done generating with the option of turning it on and off. (Bell icon somewhere in SE)

In Story Engine, because it can take several minutes to generate prose, can you add a little ding/ping/alert sound when it finishes generating? So we don't have to keep watching or checking on it? I know I'm supposed to watch and pause to make changes, but sometimes I don't want to do that. When I'm busy with other things but I would like an alert for when it's done. Is this possible?
