Can I trigger my performance scanrios based on tags/markers in k6

I have 2 different files that have a couple of test scenarios. I can trigger all the scenarios using file names but I am required to trigger specific test cases based on tags/markers/categories.
Another problem is for 1 file I have cases that I execute in parallel and for the other i have cases that I trigger in sequence.

Sorry for the delay in getting back to you. I don’t quite understand what the ask is here. Could you please elaborate on what the issue you are facing and how you want to try and solve it?
