An easy method of work regarding the task is to place something - known as an empty in Blender etc - on each of your layers. Work on the lowest layer in your stack. After doing your grouping, you can relayer your stack by - ungroup your new item - select each individual component - group it to the empties in your layer stack as appropriate. Remember, all regrouping goes up to the highest level chosen. If you are working on a bottom or lowest layer - and group to a higher level item - the entire new group will deposit on that higher level. This is a time consuming process, but it is probably the most efficient.
