Sorry, I don't know what you mean with "Import/Export icon". My best guess is, that you mean where to find this specific "gear icon" maybe? In my previous answer, I'm using the "Favorites Palette". It's located under the menu "Window -> Palettes -> Favorites". (Step 1 in following picture) It looks very similar to your screenshot, but it's a different Window! (You are accessing the favorites in the Curtain Wall Tool Settings)
I've made this step by step guide in case you are stuck at a different step.
