“To change the width of several nets:
Navigate to the PCB editor.
Select "Rules" on the top left panel and "Add Ruleset".
Select the new ruleset, and in the right-hand panel, name the ruleset via the designator at the top.
In the "Selector" tab, add the designators of the nets you want to modify the trace width.
As shown in the example above, you can select nets using the "#" operator. You can also rename nets by bringing up the context menu for objects in the object panel.
