It would be really cool if we had a checkbox or button to automatically center a ceiling grid or tile inside a room or ceiling sketch boundary. I find it to be too many clicks and time consuming to do this with every ceiling. If I could select all ceilings then check a box to center all of them at once, that would be huge. I realize they are placed originally with the grid centered, but if the sketch or walls move, they have to be manually adjusted with dimensions strings and/or the modify tools.
