Multiple Bar Countdown Alert Audio Sounds

It would be great to have the option of different sounds for the Bar Countdown Alert on each timeframe.

For example, the default audio alert for a one minute chart, but enable the option to select a different audio alert for a five minute chart, fifteen minute chart, etc.

Just having the ability to change the alert sound would be good enough (for me). The current bar countdown alert is nothing compared to what I can choose as a price alert sound. I need something to really catch my attention and the pitiful bar countdown sound is not sufficient right now.
