It would be amazing to see the whole formula with the results like that inserted into the whole thing.
So a formula like: IN([EmployeeID], Employee_Table[EmployeeID]) would give you something like this:

IN([EIC83LS], {IELJVHA, IKELVHW, 8VWLVBHYS, IVIWLNV, EIC83LS})

So we can literally see the final result of the formula.
