Change the 'x' remove button in the cart for a '-' (minus) button

[tinkertrain]

Hello!

 

I was wondering if this was possible, right now (using prestashop 1.4.6.2 and the official 1.5 theme) in the ajax cart you can see all the items added to the cart by the customer and next to each a little 'x' button that removes the item from the cart, the problem is it removes it regardless if you have one or ten.

 

When you go to the page to check out the cart contents you see the quantity column with two buttons '-' and '+' clicking the '-' removes one from the quantity not the whole product.

 

The question is, is it possible to have a minus like that in the ajax shopping cart instead of the 'x'?

 

I'm an intermediate skilled developer but I haven't been able to figure it out by myself so I thought to ask for some help from more experienced presta developers.

 

Many thanks!
