Styles of frames in inspector [Inspector]

Noticed that [Vertical and Horizontal Frames] do not have the ability to "Save" (S-symbol) within the inspector their styles related to their margins like: Left/Right Gap + Width for horizontal or Top/Bottom margins for Vertical. Maybe they don't even have corresponding style information. Is this a conscientious design decision, or rather yet to be implemented?

Of course there are new inspector designs in the works, but I wonder if there's any reason not to allow for the mentioned qualities not to be given actual styles so that they be allowed quick access to "save" through inspector usage quickly. I find myself having to spend time making horizontal frames, for example, be in uniformity through continual 0.00sp adjustments rather than having them follow a default rule.
