Is it possible to create a visibility filter that uses phasing to filter elements (if element is in existing phase, override its patterns to gray)? For example, on my RCP, I need to show my existing ceiling grid grayed out, but I still need to show any new ceilings in bold. I realize that the phase filter and its overrides were designed for this, but unfortunately it only applies to the perimeter line of the ceilings - not the pattern (the 2x2 grid). Please help if you have a suggestion on how I can gray out my existing ceiling grid, while keeping my new ceilings bold!
