Interactive Labels have been developed to easily sort your imported tasks into sections, columns, and swimlanes.
To access Label settings:
Select the Board Settings Icon at the top left corner of your plan
Then Select the Label Interactivity dropdown
Lastly, choose your preferred label settings
Note: When importing tasks, if labels were previously set up the same, you can click the label to send the task to its corresponding columns. Clicking "Do this for all suitable elements" will bulk organize into the correct columns.
