Hi,
A variant can be composed of a lot of elements to choose, we have to change the price dynamically depending the element chosen, etc.
It is not something which can be insert easily in any page. It requires a lot of data, can be huge (take a lot of place) and it's quite complicated.
If you want to change the way that it is manage, you can override the view "product | quantity" in order to customize the display and the way that the system works.
It will requires some good PHP skills.
