Sorry for the long, but hopefully helpful rant.
Just to bring this discussion back to the root of the issue. I will assume most who will post on this topic DO understand how to create, edit, utilize schedules and sorting to more efficiently make large quantities of changes when modifying a parameter which is being colored by a scheme. None of that was ever the issue here. The issue is SIMPLE. Why can we NOT change a room or area's parametric value in the color scheme dialog box. I know HOW to manage it with the current system, but I am not willing to accept it as the best way it COULD BE.
Scenario: We have created an existing program plan for a 300,000sf school building. We have colored the hundreds of rooms by utilizing the Department parameter within the Room properties. After creating the plan and assigning each room the Department title, the owner informs us that one of the department title is not the correct title. WHY IN THE WORLD can we not change that title in the color scheme and have it correctly modify EVERY room's department parameter value? I don't need to hear all the ways of how to make it work with the current setup, Trust us, WE KNOW. We want to be able to make the change in the color scheme AND keep the color.
Until then we will continue to sort working room schedules by the parameter being colored and not "Itemize every Instance" so that we can in one single typing action change the Parameter input, then open the color scheme and modify the NEW assigned color to the exact same group of rooms, such that it matches the color we've already assigned to that group(which is no longer applied to those rooms), just under a different now not being used parameter value, which we now have to delete to remove from the color scheme.
Is this is a HUGE time sensitive deal? Not really, but it also doesn't seem like a major change to make this process actually work well in a design helpful way.
