BNC Schematic Symbol (2 pins) to PCB Footprint (5 pins) best practice

Hello Everyone,

I have a BNC connector that physically has 5 pins.  A typical BNC schematic symbol only has two pins.  In the past I've simply made a new schematic  symbol with 5 pins, four of which are ground, and called it a day (schematic symbol pin count matches pcb footprint).

Has anyone figured out how to use a 2 pin schematic symbol for the 5 pin part?  I'd like to clean up future schematic and avoid having the extra pins.

I typically shy away from having a schematic symbol pin count differ from the footprint but am willing to make an exception in this case. 

Would you leave it as a 5 pin schematic symbol and call it a day?  Would you "clean" it up and somehow make the BNC connector have 2 pins in the schematic?  If so how?

BNC_2pin, BNC_5pin, BNC_part

Thanks for any inputs.
