Is there a way to filter the store to "hide all purchased" products?

In order to find some products I do not yet own I am looking for a way to filter the store.

1st step:

I selected DAZ originals.

http://www.daz3d.com/daz-originals/

k. Now 5063 products are displayed. I probably do not own all of them but as far as I can tell a huge amount of them.

I can come up with two ideas to speed up the search.

Idea 1: A filter to hide all purchased products in any category.

I guess this would be the quick and painless solution. Is that allready implemented somehow and I did just look in the wrong place?

Idea 2: in the product overview display a "purchased" button instead of the "add to cart" button.

It is very much appreciated that on the individual product view the "add to cart" is replaced with "purchased".
Having the same functionality in the overview where up to 60 products can be displayed would also speed up browsing through the "new releases" category on a daily basis.

In any way I guess having more ways to quickly see which products are allready purchased and which not might be helpful in many situations.
