Cusomizing sub-tasks based on the issue type

[Bharadwaj Jannu]

I defined a number of sub-tasks issue types in a project like subtask1,subtask2,...,subtask10;

When I try to create a subtask,

I need to display subtask1,subtask5 for Bug

I need to display subtask4,subtask5 for New Feature

and soon.

How can this be achieved?
