You can add special panes/external windows into your ClubZone store.
First off, go into your "Store Front Settings" and scroll all the way down to the bottom. From here, you will see the Special Panes section of your backend.
Click on "New" once you've done this and you'll have another window pop up.
Here you can name your content, copy and past the URL designed to be embedded as well as adjust the positioning of it all.
