[FEATURE] - How to create boxes to group connectors (possibly requires another software)

[Muzietto]

I am documenting the wirings inside my sailboat and I have made a fairly long list of cables with their connectors.

The cables connect the various electronic components in the boat (autopilot, instruments, etc.). I document their connections with those components using the "tweak/append" feature, but this is limited.

I'd like to be able to draw diagrams where the top-level components are rectangles where my connectors plug in all four sides. Something like the Arduino and the Densitron board in this example, with a lot less details in the top-level components: just four sides and the possibility to specify+order the connectors is each side.

I know this is not the purpose of WireViz.

I wonder if there is another software that can be used to draw my WireViz cables plugged as they are in reality.
