Hide Add to cart button in Warehouse Theme

[tinywhui]

Hi, I do have a question about either hiding the add to cart button of certain products, or a great 3rd party app that can help us to make bundle product.

We have some bundle products that want them to be treated as a single product. We used to use "Supply" theme before, and modify the templete file to hide the "add to cart" button, then put the link generated by the 3rd pty bundle app to that product page. But now, after switching to the "Warehouse"  theme, we noticed that the code is different, and the tutorial no longer works.

Can anybody tell us which file and which part we should modify in the Warehouse theme? Or any 3rd pty apps that could directly solve this issue?

Thanks!
