Redshift Stored Procedure Nonatomic Mode

AWS Redshift stored procedures have an atomic and non-atomic mode, the default being atomic but you can add a keyword of NONATOMIC to the stored procedure definition.  Link below:

https://docs.aws.amazon.com/redshift/latest/dg/stored-procedure-transaction-management.html#stored-procedure-transaction-management-nonatomic-mode

In DBVisualizer, if you try to add the NONATOMIC keyword to the stored procedure and compile it, it erases the word and then compiles successfully.  Is there something i'm not doing right?  It doesn't seem to matter where you put the keyword either.  We are on the latest version of dbvisualizer. 

Any help would be greatly appreciated.  Thanks!
