Shop: Cart, Individual increase/decrease quantity buttons...

First, shop is so cool. Thank you so much for all your work on it!

I was wondering if there was a way to separate the plus minus quantity buttons so that they could be styled...

I see there's a:

<button type="submit" class="remove_cart" name="del:<perch:cartitem id="identifier" />" value="1">
    Remove
</button>

Is there anything similar to adjust the quantity?

Thanks, Monty
