Branching logic in Playbooks

I would love the ability to build branching into our task Playbooks. For example, the first task may be to email the customer, but subsequent tasks are dependent on whether we receive a reply and what is contained in the reply. If no response within a few days, then the next task may be another email or a series of un-ghosting tasks. But if we get a response then that task is pointless, and instead we may proceed with scheduling a call, etc.
