I'm querying data from four columns: Column_1, Column_2, Column_3, and Column_4, and making a token for each. But I also want to create a multi value token of all the columns combined. I'm unsure how I should separate the tokens in the Token Dialog. Should drop to a new line or are they comma separated?

Also, usually, there will be a null value in some of the columns for each record. How will the multi value token handle this?
