Multiple instance tasks in BRMS 5.3

Hi Gurus.

I want to know if it is possible assign  one task to multiple actors that I assign in a dynamic way,so that way all the actors have to complete that task.

Example:One manager have to send the same form to many employees (he decide hay many employees have to respond  to that form) ,and all the employees have to manage that form and the responses has to came back to the manager whit the diferent responses.

All that happens only whit two nodes ,the first one is the manager node who decide how many employees has to response the form and the second is the employee node.
