MarketPress : Adding More Options to the Item

I sell custom made items (paracord bracelets) and I need to collect more data like

Size (should be from a drop down)
and then Color (I have like 15 colors)

then the price is dictated by what type of closure they want...

so I was wondering if the ability to add the size and color to the page was available

I would think if it isn't that this would be a feature many people would want to add...
