Be explicit, use a net port, or a wire, or a bus & port, it makes for easier schematics to read.
That said, you can draw a normal schematic wire between the things you want to connect, then right click the wire and choose to hide it, it will display basically like net ports.
Or right click on one set of the connected pins, choose Net Name, rename to the same net name as the other connected pins, DT will ask if you want to connect the nets (without a wire).
