Proposal: Mapping emojis to tags/attributes

In working with my Todo/Tasks setup, I’m used to in obsidian having emojis that are queryable for things like task priority. What I’d really like is to be able to have a setting where I map an emoji like :arrow_up_small: to “[priority: 1]” or “#yolo” such that in the markdown and the display, it’s the emoji, but in the indexing of the page and the object queries it’s the speecified value which might make queries better. Thoughts? Should I just use substring searches for emojis in my queries?
