Changing the frequency for individual tests

I have read through all of the documentation and I wanted to get clarification on network tests. Is there a way in hobbit to change the frequency of tests for hosts? Example, I ftp and http tests running against myhost.mydomain.com, can I have the http test run every 60 seconds because that's where we make money and run the ftp service check every 5 minutes because it is less critical. I apologize ifg this is in the documentation. I read through it a few times and couild not find a definitive answer. If this is not psossible, are there plans to add this functionality? Thanks
