Assign A Task To Multiple Users

I have a human task that needs to be assigned dynamically to multiple users. These users are to be identified when the process starts executing. 

How can I assign a task to multiple users dynamically without using groups? Of course, whoever claims the task first should be the only one to execute it.

 

 

Hi,
Have you thought of using Multi-Instatiation with early completion criteria.

Thank you. I was able to do it.
