Change DMS Type from Full Load to Full Load and Ongoing CDC

When I created a DMS Task in the first instance, I chose Migrate existing data. I now want to change it to do CDC as well. There doesn't appear to be an option to modify this. Can anyone confirm that I have to recreate this DMS task? I just want to know before I delete and recreate to make sure I've no option but to do just that. Thought this option to Modify the migration type should be there especially on a testing phase scenario. Thanks.
