Custom detailed opening dimensions

[MarinRacic]

Right now AC gives us the opportunity only to show opening's detailed width/height by placing the width above the dimension line and height below. What I'd need is the ability to place these dimension texts both above the dimension line and separated with a slash (see attached screenshot).

IMO, we shouldn't have just these two options available, but we'd absolutely need some kind of drag&drop wysiwyg method of placing the desired dimensions (for example, sill or transom height).
