This comes up quite often in the forum in different forms. This is the latest example: https://forum.kicad.info/t/create-a-footprint-with-common-pads/14777

To be as flexible as needed, this feature should allow selecting either one OR many pads to be connected to one net from the board editor. Think about a micro-usb connector through hole component where e.g. 4 shield pins can be connected to GND. Not all of them need to have GND contact and it could be decided when laying out the board.
