Is it possible to create a proxy user as a placeholder for resources that are not constant through the life of a project. For example, we have a central team of 5 people with whom tasks/ user velocity can be measured but There is also a rotating pool of 20+ people who can help on the project for 1-3 week intervals over the course of the project. I do not know when someone will be available but would like to be able to track how many FTE's of effort are needed per sprint.
Would also like to create a release burn down and it seems stories must be assigned to users in order to do this.
Can you tell me if the proxy user option is available? And if there is a way to see a burndown of all tasks and not just the ones assigned to users.
