..SHIFT is normally for consecutive elements...

The thought has occurred to me too, but I suspect there may be a reason for this in SH3D (?). Anyway, now I am used to it and selecting copying and pasting all sorts of combinations is easy. In fact, learning how to select, de-select toggling lock-plan, area select and item select with SHIFT / CTRL was time well spent for me.

I see the point with a list of walls, rooms etc. but I doubt it would of much help to me (too much information).
