Hi,
In that case, you need to perform an override of your view "checkout / step" and add some code to display manually the module in the place you want (depending the step page).
With HikaShop 2.x, the easier solution is the customization by override. Otherwise it is still possible to create new blocks for your checkout workflow but the development will be a little more complicated (for a more flexible result).
