When Rolling up SharePoint List Items or Documents, it is often required to also display custom columns from within the SharePoint lists or libraries. Whether these custom columns are custom columns within a list or library or Site Columns, The Lightning Conductor can display the values from them. The custom columns will show as an available column within the Lightning Conductor if the column is in common across the lists and libraries within the scope of your rollup. If it is not displaying perhaps because it is not common across all lists and libraries within the scope, you can select a specific list or library to act as a template of available columns.
