Preview Changes Before Purchasing?

Will it ever be possible to preview changes made when purchasing items in the store before actually using ATS Points to buy them? For instance, I accidentally forgot the final F in the Color Code for White (#FFFFFF) when buying my new background, and now it's this girly turquoise color.

Is there any way, or will there ever be a way to preview the changes made to make sure you want to spend your points on them?

Thanks.
