It kind of feels like a somewhat odd button, currently for styles the swatch button serves another purpose of showing the color for the style. The button you're asking for would not serve any other purpose and could easily be confusing for people who would wonder what it was for... If you had any other idea for implementing it that would not have that kind of problem it would be easier to get it done sooner.
