How to save multiple layers at once?

Hi, i have a question. Is there an option to save multiple layers but first image need to apply do all layers below. I know there is option for that in photoshop but it's not working for me. Im creating t-shirt mockups and i will leave screenshot so you can better understand what i need if possible. So as you can see on image the frist layer called army dad need to be visible on all t-shirts below, i can turn off/on layers and save them but it will take me some time to do it because i have over 1000 images... So is there an option to somehow save them all at once but design need to be visible on all t-shirts? Thanks
