I don't believe it's something you can acquire ingame through any known process. either the coach comes with it, or he doesn't.

in the case of a positional coach, if they didn't come with it (most don't, but a few do), you can in theory promote them to coordinator and buy it then, but you can't demote them back to positional coach (not directly anyway) so it doesn't really matter.

Since you can do neither with a trainer (or GM, though I've never heard of an ambitious GM, now I wonder if there might not be one), he either comes with it, or he never gets it.
