Can you add complications to watch face?

Ok, so I know how to change complications and download third party complications. But is it possible to add more than allotted to a certain face? For example, I would love to use the photo watch face, but once I display the time on the bottom right with the weather and date there are no complications slots left. That doesn’t work for me. I would love to add two small complications (likely reminders and calendar) to the upper corners but this doesn’t seem possible, making the actual range of customization feel veey limited.
