Not possible with a few clicks. There is a couple of options. One is to take the KiCad design files and modify them (if you're new to this it might take a long time to accomplish plus it is easy to make a mistake), or you could do a new design from scratch (this will take even longer, but you will gain a lot of knowledge).
I would recommend using the given design. Just be careful and you will succeed.
