Customer Artwork Editing on Quote

I would like to see where customers could edit the artwork itself and/or placement on the quote level. Having granular control over what the customer is capable of editing would be nice too such as font, size, color, decoration type, location, quantity of decorated areas, total sqin/stitch limit. With a total sqin/stitch limit, you could then on the backend have a "maintain the same price, regardless of customer changes" to where the customer can make little corrections themselves and they would be able to speed up the process by making the necessary changes themselves and they can accept the quote when they are finished or it could go through a final approval to the store side.
