yes, those sa are specific : dribbler, penalty specialist, 1-1 and p.m. (this is questionable if affects in a passive way too).SA could have an effect without being visible when watching live animation.
During live, when a s.a. is activate, we see the sign.
Def. wall is activate only vs F-K and "header" vs corners.
If we have a DC with "header" who's scoring more often from C-K, it's not because of the s.a. but from his "talent"/internal programming.
