You have full control over the overview panel inside a production code — which lines are shown, grouping, and what counts towards the final forecast. You can create different default views for different groups.
How to do it
Open a production code and click Edit on the panel.
Bring up the variables you want to show, group them (for example «Change Orders Sub»), and use bold text where you like.
Choose to hide lines with zero values, and mark what should count towards the final forecast.
Save the view — for the whole project, or as a separate default view for a group of prod. codes.
This way, for example, the Setup and Operation codes can have a different view from the technical trades.
