Dilema with product quantity box

[seian]

Using Cold Steel template with the latest store version.

My situation is I don't like the quantity text field when looking at category product list. There is a box to enter quantity, but no button to indicate the add to cart. I know I can just hit enter in that text field to send it to the cart, but customers are used to having a button and it adds confusion.

But when I set a product not to show a quantity option, people can't even edit quantities in the shopping cart.

Is there a quick (or at least reasonable for poor PHP skills) way to:

1 allow edit of quantity in the shopping cart while at the same time-
2 add a submit button next to the quantity box in list view.
