When I use A/I servo for moving subjects, I only see 5 Auto Focus points. I would like to expand this however I cannot find where to do this. I would like to try 9 or 15.
Thanks in advance for your help.

From the EOS 7D MArk II AF Setting Guidebook:
Much of the same information, some of it in greater detail, can be found on pages 85-98 of the EOS 7D Mark II Instruction Manual (for the revised version of the manual released with firmware version 1.1.0 - the page numbers may be slightly different from earlier versions of the manual).
Keep in mind that you can only select most of these options when shooting in P, Tv, Av, and M exposure modes. If you're shooting in the fully auto Scene Intelligent Auto Mode (A+ on your mode dial) the camera makes those decision for you.
Also keep in mind that all of the AF points will not be available with all lenses. Only lenses with wider maximum apertures can use all of the capabilities of all of the AF points. As you select lenses with narrower maximum apertures you give up some of those capabilities. The narrower the lens, the more restricted your options are. That's all covered in pages 99-107 of the Instruction Manual.
Finally, depending on how some of the other many configurable options for your camera's AF are selected, the AF area may be preserved differently in different AF modes. For instance, say you are shooting in One Shot AF mode and have AF Point Expansion (8 surrounding points) selected for the AF area. When you switch to AI Servo AF mode the camera will remember that the last time you were in AI Servo AF mode you had Single Point AF selected for the AF area and will use that. To switch to AF Point Expansion (8 surrounding points) for the AF area you need to make that selection while in AI Servo AF mode. If you have separate settings enabled for vertical/portrait and horizontal/landscape orientations, you also need to have the camera in whichever orientation you wish to affect when you change AF mode and AF area selection.
