Add Drop down to store pages

Please, please add a Drop Down option in the digital art store pages to select how many items to show on one page.  Looking through pages of 18 items when there are 195 pages takes forever (pardon the pun).  I would love to see an "All" option but if that is not possible it would be great if "100" is the largest item count available.  Default could be 18 with options of 50 and 100.  Thank you for your consideration.
