I need modify a Screen of system. about the Sub-Tasks

[Rafael]

When you open the form of a task there is a section 
where you can see the subtasks associated with this task with some fields.
I would need to be able to add a couple of customfields in this section, 
but from that screen these sections do not appear, 
neither the sub-task nor the comments section.

This is not possible unless you wanted to modify the code.
