I think it would save a lot of time during initial model setup if the following actions happened when a model builder checks Numbered List within the general lists panel.
- New property within checked list created called Display Name.
- Display Name property format set to text.
- (Potential) Set Display Name property formula to CODE(ITEM(List Name)).
- Display Name in general lists panel set to Display Name property just created.
I think items 1, 2, and 4 and all best practice and should be used universally, as they drive consistency and usability in our models. I follow these steps for each numbered list I create so if Anaplan did this automatically it would save a lot of time.
