How To change Function List's Order or Sorting it

How Can I Reorder or Sort my Function list on Button’s Onlclick Event?


Like this one, It is DropDown OnValuedChange Event’s function list

Currently My Button’s Function list is Same as this Image


It is so Hard to recognize my Custom void, while it is in middle of many Default functions in Monobehavior

It would be much great if there are ways that I could sort this list or reorder
