How to update "local" dimensions with new values in the new model?

Hello,

after creating a new model with some dimension I have mapped the data and got the issue, that the data cannot be added, because it is not known in the dimension.

After a bit of research the old model has a setting for this kind of issue:

By selecting this option new entries will automatically added to the dimension.

Now my question: Where can I find this setting in the NEW Model?

Best regards,

Tim
