Current user email in anonymous task

Is there anything technical preventing "Context > Current user > Email" from being used in an anonymous task in NAC? The task urls are unique for the different users in a task so it makes sense that we should at least be able to identify the source of the task, whether it was user 1 or user 2 etc. Is there any plan for this capability? The email addresses are listed under the tasks in the Tasks page of NAC with their appropriate task links. Where is this association? Is there any way to access it within a form/workflow?
