The toe is adjustable, but they're speaking of toe change due to camber change. In theory, the toe is dependent on the camber angle, but the reality is that with the geometry of the stock-ish front end, the actual change in toe is so minimal that you can essentially discount it completely.
Trust, but verify: With the camber plates full outboard, set (or measure) the toe angle, and then dump the plates inboard. Settle the suspension and re-measure. with the old-school string method, the difference on my car wasn't enough to even mess with. This was verified on a Hunter alignment rack, as well...
For "presetting" street and track camber angles, a sharpie is your best friend. Scribe two lines on the top of the tower, and when the strut shaft is centered on the outside line, you're at the street angle, and on the inside line, you're on the track angle. You COULD scribe a line every 1/4 degree if you wanted to be snarky, but I wouldn't bother.
