the power of Revit schedules is great, allowing a global perspective to manage the contents of our projects, especially the multicategory ones, but they lack a couple of capabilities to achieve this true cross cutting vision. unfortunately, Revit uses a few different parameters to handle levels, depending on each category. most of them use "Level", but walls use "Base Constrain" and roofs use "Base Level". that small dispersion prevents a whole level organization. a simple solution would be to add new "full level" argument to join those three parameteres in a single column/filter.
in the case of "Phase Created/Demolished" it should be much easier, since they actually have the same parameter, so it would just be a matter of adding it, that's it.
