This might be useful for people wanting to play custom Pushover sounds.
I know this is an old thread but I wanted to share how I overcame this limitation. I use custom Pushover sounds (“gate open” “front door locked” etc) instead of the built-in Pushover beeps and blips.

This rule makes my tablets play “open” or “closed” notifications and sends a color-coded message to my Pushover app.
Here’s the POST unredacted:
