David,

Another question about the Revit Renumber tool now that I am giving it a try.  Sorry, I am not sure if this is the forum to keep asking questions, but hopefully I'm just overlooking the answer.  Is there not a way to give identical pieces the same part number and also select the order you would like to tag? If I check one, the other gray's out(screenshot below).  It's not the end of the world if my part numbers jump from piece to piece but, wondering if there is a way to make this happen. 

Thank you for all the help
