You cannot create you own custom refactor options. You only see the Refactor options inside the VA Snippets editor so that you can customize the available refactoring options.
For what you are trying to do using the normal Snippets is your only route. There is a case # out there that is supposed to add some of the refactor keywords to normal snippets. I don't know the number off hand, or how many keywords are to be supported outside the refactor options, but I'm sure feline can find that. :)
the case for refactoring tokens in normal snippets is:
case=3204
Here you can use both $selected$ and $clipboard$ so with a bit of care you can have a normal snippet do this, using $clipboard$ for the type and $selected$ for the symbol name.
