Duplicate Manager Names at Different Levels

Anonymous , One of the solutions I can think of is to have the employee name/manager name in a disconnected table. Then you can filter the values selected in one or more column

example countrows(filter(Table, Table[Level1] in values(mgr[empname]) || Table[Level2] in values(mgr[empname]) ))

This is suitable when you have multiple columns, if you have only one column as manager id a duplicate table or inactive join  can help
