Can I make all "add: 0" input boxes on product pages to "more info..."?

On product listing pages, products that have attribute options display "more info..." link to the product info page. Products w/o any attributes have an input text box that displays "Add: QTY". Is there a way to just make all products have the more info link on the listings?

Example on my site: http://www.stevekwebdesign.com/index.php?main_page=index&cPath=92_97

notice there is a Add: QTY box and more info links on the listing page. I want all just the more info links

Not quite, but by playing with the "Display Product Add to Cart Button" and "Info Display Multiple Products Qty Box Status and Set Button Location" switches on the Admin > Configuration > Product Listings page, you can get rid of the quantity boxes.

NOTE: If you are wanting the Product Listing to actually never show the Add to Cart button, never show the input box and only show on products with or without Attributes the:
... more info

link, then you can use in the Configuration ... Product Listing ... and set this to 0:

Display Product Add to Cart Button (0=off; 1=on; 2=on with Qty Box per Product)
Do you want to display the Add to Cart Button?

NOTE: Turn OFF Display Multiple Products Qty Box Status to use Option 2 on with Qty Box per Product
