Button Cover for Part 103 Without PCB

We have a GE Microwave, model PVM9195DF1WW, at our old house, and the timer button has broken; it gets stuck under the outer panel when pressed. After taking apart the panel casing, we found that the problem stemmed from a broken spring; each button on this component has two plastic bars that function as springs to pop the button back up after it's pressed, and one of the springs had broken. The specific part is seen in front of Part 103 in this diagram; this site lists the part as a SWITCH PCB, ASM. The "ASM" part seems to mean assembly, which would mean both the circuit board with the actual buttons and the plastic cover with the button faces. I only want the plastic cover, because presumably it would be less expensive, and I also wouldn't end up with a loose electrical component that I don't need. Is there any way to get only the plastic piece?
