A:Answer Yes, but only after modifying.
Carefully use an an exacto knife or other sharp knife such as a box cutter, carefully cut around the circle mark you just made, scoring it but not cutting all the way through.
Next slowly work at getting a small area cut free and work to lift that area up while carefully cutting, tearing, and pulling until the circle of fabric is removed.
Next, attach the pop socket to the smooth underside of the case and enjoy. For a more secure attachment a certain retailer named after a Brazilian rainforest carries a product called pop-tech that has replacement stickers that are 3M adhesives, and they really do a good job at securing the pop socket to the case.
