Classifying a message

If I have an AI task that classifies a message and then stores it in a variable should that variable be a list or individual variables: i.e.

MessageType {
  Sales,
  Vendor,
  Complaint
}

VS

IsSales
IsVendor
IsComplaint

@ericallenpaul It should be individual variables as of now, although it would be quite cool to add support for enums in the future!
