unfortunately, it is not possible with current implemented features. BPMN2 spec defines completionCondition that is evaluated at the end of each instance so that could be something useful for you but it is not yet there (you could open jira issue)

does that mean you would like to assign different names to the task instances that are part of multi instance? Where task name is a data input definition and can accept expression same as GroupId. With that said your collection that is an input to the multi instance does not have to be collection of simple types like String, it could be collection of objects that can be then used to resolve the names and actors that you'd like to assign task to

if your object would be like this:
     String actorName
     String taskName

then you fill in collection with instances of TaskAssignmentInfo object and pass that collection as intput to multi instance. Then in the task definition you declare that the item that will be put into task instance is taskInfo and you can refer to it for interested fields to set data inputs:
taskInfo.getActorName() to assign task to given person
taskInfo.getTaskName() to set the task name dynamically
