I have loaded table - fields are : CustomerID, Manager, time. Last one is numeric value (total time spent etc).
Most of the time there is only one manager per client, but not always.
Now I need to create filter named "managers", where values are : if there is only one manager, then "Manager1", if there are two managers involved then (Manager1, Manager2), if there are three than "Manager1, Manager2, Manager3".
