How to hide / disable change task soft type according to change notice soft type

Hi All,
Ie any way to hide / disable or give pop up message to user when he select in appropriate change task type while creating change notice.

How we can restrict user to select certain types of change task only for perticular type of change notice.
Ex.
Change notice A
Change task a
Change task b

Change notice B
Change task c
Change task d

Thanks,
