    1) If they're on different layers and can be connected by pins or vias, add the NET_SHORT property to the connecting pins or vias.
    2) Add a zero-ohm resistor to the schematic connecting the two nets together.
    3) Create a fake part with an surface pin the size of the connection you want and use the NET_SHORT property.
    4) Use static shapes and waive the DRC.

    A fake part can be created with an surface pin OR a internal pin.(net_short, of course)
    Work's fine also.
    The "little" problem with a fake part: it should have a place_bound so a drc appear if the "join" is done under a component: you will have to edit the fake's boundary or waive the drc
