There are times when it's more convenient to map an iteration of a loop as a non-looping element (so that you don't have to bother with specifying a loop expression). This is easily handled by unrolling an element from a looping element. Do this by right-clicking on the element and selecting Unroll from Loop. When you unroll an element from a loop, it creates a new non-looping element that you can map more easily. You can create as many of these as you like. The looping element is kept after all of the unrolled elements. If you no longer need an unrolled map element, simply delete it.
