Redmine

Hello,
is it possible to inherit parameters of subtasks from parent task ? For example I have task, that has several subtasks and want to increase priority of all subtasks (full tree, including their subtasks etc.) Another example - change due date to parent task will change due data of all subtasks. Is that possible to do using some plugin or setting in redmine ? P.S. I don't want the opposite - available in settings?tab=issues - inherit parent tasks attributes from subtask.
Thanks for help !
