Hi Mark ,
You wont be getting the list 'refrenced' by as the same way you get in - Modules, but what we do is as per below
Modules - Applies To - Copy & Paste and find out the list used in diff Module's .
Proabaly this feature will be included by Anaplan, currently we uses Subsets and i think they are figuriing a way to how to incorprate both 🙂
Export the line items data that is present under Modules --> Line Items tab.
In the downloaded excel put a filter to the Format column and select the desired list this way we can find out in which modules a particular list is being referenced.
