Default busses "bus" or "from_bus"/"to_bus" should be mapped using structure if possible.
Thus, for single "bus" - look if there exists a single input our output - if so, use this as "bus".
For "from_bus" and "to_bus" look if single inputs respectively single outputs entry exists and use this one.

This can only be done if mapping is 1:1
