Running subsets of supertest tests

I haven't been able to find any detail re running subsets of SuperTest tests. We currently run subsets of (Selenium) UI tests using feature @tags set with ~config.js. Is there something similar in Supertest? Ideally I wouldn't have to add more scripts to package.json to do this. @tags would be a great feature addition? Apologies if this is the wrong forum for this question.

UPDATE: I've found a few options (see below links), but still not something as flexible as a @tag approach...
