Need customization on my website

I have a hotel booking site which does the checkout at the end with woocommerce. Here is the following problem, that when I currently add a room and want to book the same room category again on another date, that the 2nd adding of the room in the cart overwrites the 1st room. Can you help me here that this does not happen and that the 2nd room is added to the 1st room in the cart?
