In workbooks that include a hierarchy panel, where are new columns added based on user selection?

In workbooks that feature a hierarchy panel, new columns are added to the left of the defined columns based on user selection. This organization is designed to enhance clarity and usability by placing new, user-selected data in a position that visually differentiates it from the existing defined columns. By adding new columns on the left, users can quickly identify the newly included data as it relates to the existing structure.

This layout supports intuitive navigation and aids users in understanding how the selected data integrates with and influences their current view or analysis. The consistent positioning also fosters a better comprehension of spatial relationships within the data, thereby streamlining the user's workflow.
