Total budget of Subtasks at the Task level

Hello!

When adding budget or cost of a subtask, the subtotal does not appear against the task. 

I suggest to enhance the feature, and add another option on the column level properties (subtasks and tasks) to choose from.

That tool will allow us to see a total amount of the subtasks against the task, and grand total of all tasks at the project/folder level.    

Thank you!
