How to detect emojis with BuzzKill?

I have this one app that sends all of the notifications under the same category so there's no way for me to filter promotional notifications from the notifications that I actually want.

A pattern I notice from the app is that promotional notifications always contains emojis such as 🎉 or 😱 for example, so I wonder if there's a way to just dismiss all notifications from this app that contains any emoji at all?
