We built labels similar to Github's so that you can organize reports effectively
Create your first label

Once you are in the report list:
a) click on the Labels section in the top right of the page
b) click on Create a label , add a name and pick a color
From a specific report
To create a label, or select an existing one, from a report just click on Add label and you'll end up at step b)
Mind that you can add multiple labels to the same report!
