So I figured out what I was trying to accomplish. I've listed them in sequential steps. If someone want's to review and let me know if this makes sense or if there's a more efficient way to create a new hole in one component body and then move it so it snaps to/aligns to an existing hole in a different but adjacent component body, please let me know. Thanks to everyone for their input!
*With the entire Assembly activated:
1.) Create the desired hole (Countersink/Simple/Flat) in "Component A"...the tabletop.
2.) Select 2 Faces: The conical countersink face, and the bore's face...or simply select them once you've clicked on Move/Copy.
3.) Right-Click and select the Move/Copy command. If not done in Step-2, then select the two faces of the Countersink Hole.
4.) For "Move Type", select "Point-to-Point".
5.) For "Origin Point", select center white dot of the bottom face of the new hole's bore (holding down the CTRL key if on a Windows machine to keep snap points and mouse from jumping around).
6.) Hide "Component A" temporarily so you can better access the top face of the existing hole in "Component B", the table's frame.
7.) For "Target Point", select the white + or dot at the top face of the existing hole's bore.
8.) Click "OK".
Using the "Move/Copy" function of the Right-Click menu should have been more intuitive to me since what I was trying to do was "move" a feature like a hole. I was just making it out to be or thinking it was harder than it actually was.
shahriarsifat1802164, your suggestion mentioning to select multiple faces is what clued me in.
Surprisingly, there isn't anything this basic but straightforward that addresses moving or relocating and aligning holes anywhere that I could find....including on YouTube.
I wish that the Autodesk Screencast Recorder would format correctly on my HD monitor so I could capture the above steps in a screencast recording. Thanks to everyone who responded.
