At the moment we can only redefine a layer combination (eg "Elevations") by selecting the required layers from a very long list of layers. This is tedious.
I like to select which layers are shown on my elevations by looking at the display window, and using the Quicklayers palette "show/hide layer" buttons. This is much easier than selecting from the list.
Having got the correct combination of layers to display, I would like to click a new button that would update my "Elevations" layer combination , telling it to "redefine with current window settings".
This would save a lot of time, and also prevent bad habits of "custom" layer combinations.
