Include quantity / variations directly on product listing

Hi I'm building a site for a shop that sells jewerly. More tahan 90% of the sales consist of 30/40 products aprox.
They asked me for a quick way for the buyers to make an order.

1) Is possible to include quantity for each product on product listing?
2) Is possible to include variations for each product on product listing?
3) Can I have both included :slight_smile: ?

Customers usually don't need to take a look at product detail, so I'm wondering if they can choose quantity and variations right from the product listing. This will make a huge speed improvement to the process.
