David,
This is definitely possible using Custom Actions and Workflow rules. The question is what exactly is the use case. What do you want to base your approvals/rejections on within Tasks?
For further clarification, we suggest you register for one of our Advanced Q&A webinars (see the link-> http://www.clarizen.com/resources/online-demo.html#second ).These are great resources for free consulting with our Customer Success Managers and visual answers to your questions.
Sincerely,
Boris
