How to get 'other items from this collection' with add to cart on product page

We sell furniture so we are selling a lot of items that belong in collections such as full bedroom sets, living room sets etc and want to make it as easy as possible for the customer to add other items from the same collection to cart while viewing a product.

Sort of like related products but for products in the same collection only.

Would appreciate some help with this is possible please if there is an app compatible with Magento 1.9 that can do this or something similar for me.

I am using the Ultimo theme.

Thanks!
