Multiple instances of subprocess. how

I assigned the fist task of the subprocess to a group.
As soon as a member claim it and the task gets completed, the subprocess finishes and I cannot execute other or multiple instances with other users.
How can I achieve it with modeler?


In the case when cardinality of the task set is known when the the first task is created use multiinstance tasks.
In the case when the decision whether the new task is created or not can be evaluated when task is completed, add exclusive gateway and loop back to the process model.
