Adding Quantity Button and Select option to the featured page

Hi everyone.

I'm trying to replace the "add to wishlist" button with the quantity button and also trying to add select option to select product size so the user can just add the quantity and select the size they want right there, instead of clicking on the product link.
Does anyone have a practical solution to this ?
My opencart version is 3.0.2.0

There might be available extensions on the Marketplace that could do this. I would suggest to take a look at them by using the Marketplace's search engine.
