Due to space constraints on a PCB design, I have a need for partial depth holes in a 2 layer board. This would be in a 62mil thickness 2 layer board, and the finished depth of the holes would be 45mil. Each hole would be 26mil in finished diameter and centered in a pad of at least 50mil diameter. At this point, I am unsure if they could be finished with copper plating or not, but my PCB fab says that they can manufacture partial depth holes. Does anyone have experience with partial depth PCB drill holes? And how would I enter this information into Altium Designer? I could use a fabrication note, but would rather have a more solid way to enter this information directly in the Gerber and NC drill files so that the Chinese manufacturer knows exactly what to do. I read somewhere on here that you have to enter this into the PCB files and it's not possible to have it in a library component.
The specific component that will fit into the partial depth holes is a press-fit Mill-Max pin.

What you are talkign about is a 'blind' hole. This technique is often used on multilayer boards for vias, so they do not go all the way through the board. You can also have buried vias.
