Prevent Subscription to report from running on a holiday

I have a SQL Server that I am using for building and distributing reports. I have built all the packages for importing data as needed as SSIS packages. These reports only need to be run after the data has been imported. I have built my SSIS packages to check and make sure that the day isn't a holiday by comparing the date to a table that contains holidays. This way my data is only imported on business days. The problem is, my report subscriptions are set to run at a specific time Monday - Friday. How can I programmatically run the subscription at the end of my import, so that it only runs on the days that the import runs and not on the holidays?
