I'd be happy to offer some advice but I'll need more context on what you're trying to accomplish first. Can you take a screenshot of what your current product setup looks like and how you want it to be organized?
Example: You have a red t-shirt in a collection called 'clothing'. The red t-shirt is currently on the first page but you would like to move it to page two?
If there is anything else I can help you with, please let me know.
