In addition for phasing, need the ability to better control phasing. An issue that I am having is that I have a new wall type and set it to existing. If I use the override in the phasing menu (previous and new) it greys it out. if I have this as by category for existing wall then it shows the hatch pattern for a new brick wall. My work around is to have a new type of wall which I have called existing and removed the fill pattern from it. I realise one can override individual elements by select them and right clicking and overriding by element. the becomes a bit tedious if you for argument sake have 100 existing walls. I have tried to modify the phase fill pattern to be a solid white fill, but this doesn't seem to have any affect, again forcing me to resort to creating an existing wall type in a wall family. Due to this lack of better control feature for phasing I am required to create the same wall/floor/roof... 3 times. Once as new, once as existing, once as by others.
The reason by others, is so that I can have grey walls for the neighbouring houses here in the UK, where neighbouring houses share a common wall. And that way when I render views the neighbours houses are greyed well even existing walls for the project appear in colour
