How to add triggers to SPOTLIGHT as an app?

I want to specifically utilize Key Sequences/Typed Words and associate them with opening files quickly or executing scripts. Right now I have them under the condition "focused_element_detail" but its finiky and doesn't always work, especially if i activate spotlight and type quickly after. I want to utilize the app specific feature (left side of BTT) but can't figure out how to add it as an app. Any help much appreciated!
