Infamous? I think I'm okay with that...
A lot of the information in the room schedules and window schedules is 'dumb', as in I just found an empty parameter, labeled it what I wanted, and filled in the information.
If you open up the schedule (in v10, I'm guessing), go to Scheme Settings and choose an available parameter that will allow you to type in whatever number/text you want. If there isn't an unused user defined or custom text parameter available, go to 'Additional Parameters', find the object you're using in the folder view, then add a new user defined parameter. There should be plenty. Once you've added the new parameter to the schedule field, you can rename it in the actual schedule.
Hope that helps. Feel free to PM me if you have any specific questions about standards or other things I tried setting up back in the day.
