Can i create a new screen in an activity with more than 4 fields?

I want to have a screen for skiing with more data fields all on one screen than are in the existing built-in screens for that activity. When i go to "add new" and then "layout" the most data fields i see offered is 4. Is there a way to get a screen with more than 4 on it, without becoming a software developer and learning a programming language? I see posted screens in IQ with quite a bit more fields on them, but do not see a way to create those from the watch.
