Afaik, grounded normals for the most part can be done either crouching or standing. If there are any specials that can only be performed as such, they're most likely far and few between and/or game specific, and the only thing that immediately comes to mind are command normals, but we all know the situation for those.

I dont think it needs a property icon, just a mention in the description.
