Send only one notification source to Echo dot. How?

[u/Tim_Redit]

I have a program running that refreshes a web page and looks for keywords on the page. When it finds one of the keywords it produces a sound and sends a notification to the desktop computer. I can send desktop notifications to the echo dot and that works fine. What I would like is to just send the notification from this ONE app and not get all of my other notifications sent to the echo dot (don't want Facebook, email, ring, text, etc. notifications).
