Empty option for choice node

[zna5368]

Problem Statement

If you have a choice block, there should be an option that allows you to do nothing. The closest I was able to get to this was adding just a space, but that looks bad.

snippet class "Create a new class"
	public class ${2:$TM_FILENAME_BASE} ${3| ,extends,implements|} {
		${0}
	}

Ideas or possible solutions

Maybe add some special choice like $EMPTY which will not do anything if you choose it:

snippet class "Create a new class"
	public class ${2:$TM_FILENAME_BASE} ${3| $EMPTY,extends,implements|} {
		${0}
	}
