Variation Products

I am using the product variation, in the product page it will popup with the products options are listed.

curently each product with the options has an Add to cart button next to it. if i click on the " add to cart" the page will refresh and the popup closed. I will need to open the popup again to choose other products.

will there be any idea that i can add a check box for each products, so after i selected all the product that i need then just add to cart all the selected at once.

thank you,
