Midplane between Two Parallel Planes at Assembly Level

[#1]

I have read some older posts in this forum and found some work arounds, but I still don't clearly understand why we can't have the option to insert a workplane between two parallel planes/faces at the assembly level. Why can we only do it at the part level?
