Is it possible to automatically close recurring tasks when closing a milestone

Is it possible to automatically close recurring tasks when closing a milestone

Hi,

We recently decided to change the way we use Projects. 

We have created new milestones for our projects with better tasks. Now we want to close the old milestones and tasks, but when they are recurring tasks it doesn't work, we have to open every task change there recurrence to none, then close it. 

We have many tasks to close and where hoping for a faster way to do so. If you know a way feel free to inform us.

Thanks a lot
