Hello @Pedro_Mendonça,
I think this existing feedback request thread is what you are looking for, can you confirm?
And here is another one.
Another way of setting this up could be using rules that trigger and create new tasks.
So you could create a special section or custom field drop down and then if a task in this section or with a special selection in the custom field is marked complete a new task is created.
