Add a flag for overlapping poles (pole with set location on top of a pole with no set location).

Sometimes you can have a pole that has a set location on top of a pole with no set location. Sometimes it is hard to see the overlap until you select the pole and see multiple selection options. An example could be that 2 out of 3 phases are connected to the pole with the set location and 1 phase could be connected to the pole that does not have a set location.

It would also be nice for an easier/non manual method to move all attachments from the pole with no set location to the pole with a set location.
