The issue we are experiencing with the projects is when an item is added to the project, the project is accepted, then the client confirms or revises the colour or variant of an item. The items are required to be replaced on a change order, and there is no option to retain the shapes from the original item to the new item.
As an example, this is very frustrating when there are 60-odd keypads in a residence and the client opts to change the finish from smooth to textured, or white to black. This deletes all the keypad shapes on all pages from the drawings once the CO is accepted with the replacement item.
