A scheduler for the notification sound to play on the computer.

I would love it if Join for Chrome/Windows/Browser had an option to only play the sound that occurs when a notification is pushed on certain times of the day, and only on certain days. 

I am in school from 6:30 to 3 and my parents work from home. They don't like constantly hearing my computer making the happy little sound that it successfully received a push all day, and I often forget to mute my pc. If I could schedule Join to be muted on certian hours during certain days, that would be great!
