creating a wire to groups of photos and not all of them

Very new to XD but trying to create a link from a button on the home page to a selection of 'portrait' photos (I'm a photographer) and then click on another button to a set of commercial images. The problem is that each button does go to the correct image to start with but despite putting a wire on the last image of each group that should link back to the home page ...it doesn't. Once all the portrait photos have been viewed  it carries on into the commercial photo and vice versa. How do I restrict the photos being shown by clicking on each button?
