Enter number of copies to print of a form as a variable

I would like to be able to print a variable number of copies of a form by using a data field to hold the number of copies for each form such as an invoice.  In other words, I'd like to print 3 copies of some invoices, 4 copies of some invoices, 2 copies of others, etc.  For each invoice, the number of copies needed would be part of the invoice data.  Is that possible with Crystal Reports 2011?  Thanks!
