WooCommerce Product next & previous link modification

Hi,

I am looking for modification in wordpress Woocommerce product next & previous links.

already next & previous option is there on woocommerce product display. but we are looking product should be end in the single category. it should not browse all products in all categories.. it must stop in end of the product in the single category. once reach end of the product it should show next category.. instead of end link...

if any one can help us...sure I will give more projects in future....

regards,
