Processing T4's for one company

We use PeopleSoft 9.2 for our Canadian payroll. We currently process payroll for 7 different companies, all with different business numbers. One of the businesses has sold and we need to issue T4's for the employees. Is there a way to process year end for only one of the companies? All the year end reports include all the companies that we process and I so not see a way to identify just the one when we create the T4's
