The Edit Multiple Pipes command needs to have the ability to change fixture units. Sometimes I forget to add fixture units to hot and cold water pipes I'm copying to other sink or shower locations and then I have to change each one individually or erase them and copy them again after I've added fixtures units to the first one to be copied. The current project I'm working on is a large university sports complex with a lot of locker rooms so you can imagine the number of showers, sinks and toilets, etc.
