Custom countdown tone or multiple tones to choose from

The Ring entry\exit countdown tone is hard for me to hear even with the volume at the max. The tone for some reason is not easily discernible, almost soft. Compared to Simplisafe, which is more of a hard ping like sound, similar to the radar ping of a submarine. When we return home, we have to listen for the tone and it is immediately noticeable that the entry delay is running down. So I'd like something more urgent sounding and discernible and\or the option to choose from other tones.
