How to split surface in SolidWorks while trimming?

After trimming multiple surface in SolidWorks 2012, the resulted surface is merged into one surface. Is there any way to keep them different surfaces?

If you use "mutual" as your option when trimming surfaces, then it automatically knits them together. So if anything just use standard trim, or just use a surfaces offset at "0" and make a copy of it.

make a sketch on the surface u want to split it,
then use split line tools to split the surface u want
