From MaxCut Version 220.127.116.11 onwards, if you are working with grouped units, you will have the option to label the panels with both the Panel Name, as well as the Group Name to which the panel belongs.
To enable this setting, go to Settings -> Layout -> Layout Grouping
Select Panel Name + Group Name and save. You can select this setting for either the screen diagram or the printed reports, or both.
Depending what selections you have made, you will now see the panel name and well at the grouped unit name to which that panel belong on the Optimsed Sheets screen and the Job Layout Report.
