Block Customer for Account Statement : Urgent pls

Can anyone suggest if there is any option to block a customer from being sent Account Statement.

We currently have a Z program, where we give a range of customers in the selection screen and it will print statements for all the customer.

But if we dont want to send statement to a particular customer, how can we do that..

Is there any similar option like Dunning block, to block a customer from being sent a statement.

Please let me know
