Is it possible to add multiple columns with DAX

Instead of adding columns one at a time using dax is it possible to add multiple columns in one go?  I can break the code up below to add one column at a time and it works, but when I try to combine it into one dax statement it doesn't. 

 

 

 

Alice =
 SWITCH(TRUE(),
 'Table'[Name] = "Alice", "Alice",
 'Table'[Name] = "Bob", UNICHAR(8203),
 'Table'[Name] = "Carol", REPT( UNICHAR(8203), 2),
 BLANK()
 )

Bob =
 SWITCH(TRUE(),
 'Table'[Name] = "Alice", UNICHAR(8203),
 'Table'[Name] = "Bob", "Bob",
 'Table'[Name] = "Carol", REPT( UNICHAR(8203), 2),
 BLANK()
 )

Carol =
 SWITCH(TRUE(),
 'Table'[Name] = "Alice", REPT( UNICHAR(8203), 2),
 'Table'[Name] = "Bob", UNICHAR(8203),
 'Table'[Name] = "Carol", "Carol",
 BLANK()
 )

Hi @barrymac98 

If you want to add multiple columns at one time, you need to use calculated table, because it will return multiple columns, you cannot create them directly at the existed table. you can refer to the following sample.

Create a calculated table

 

Table2 =
ADDCOLUMNS (
    'Table',
    "Alice",
        SWITCH (
            TRUE (),
            'Table'[Name] = "Alice", "Alice",
            'Table'[Name] = "Bob", UNICHAR ( 8203 ),
            'Table'[Name] = "Carol", REPT ( UNICHAR ( 8203 ), 2 ),
            BLANK ()
        ),
    "Bob",
        SWITCH (
            TRUE (),
            'Table'[Name] = "Alice", UNICHAR ( 8203 ),
            'Table'[Name] = "Bob", "Bob",
            'Table'[Name] = "Carol", REPT ( UNICHAR ( 8203 ), 2 ),
            BLANK ()
        ),
    "Carol",
        SWITCH (
            TRUE (),
            'Table'[Name] = "Alice", REPT ( UNICHAR ( 8203 ), 2 ),
            'Table'[Name] = "Bob", UNICHAR ( 8203 ),
            'Table'[Name] = "Carol", "Carol",
            BLANK ()
        )
)
