Menu not in the correct order

I'm loving Storyline so far. Interaction that used to take me a day to program 10 years ago are available as drag and drop, brilliant.

I am running into some issues. One of which is the menu that is created on the left in a published project. The menu seems to be generated based on the creation of the slides. First slide created is at the top, last slide created on the bottom.

Problem is that I tend to move things around and this menu does not reflect the final version. The work around I use now is to insert a new scene and copy/paste each slide in the right order.

Is there another way of doing this because this is very time consuming and very difficult with a non linear project.

Thanks
