Auto detect network interface for "Bridged" networking

[freebrowser1]

Describe the issue
I use my Macbook both at home and at work and use 'Bridged' to allow access from inside the network because the VM runs a webserver which has to be tested from outside. Sometimes I use ethernet and other times wifi, depends on what is available / strong enough. But when I switch network type I have to fill in 'en7' for ethernet and leave it empty (or fill in 'en0') for wifi.

Otherwise the VM refuses to start with an invalid network type.

But why do I need filling in every time when I switch network type ? There is only one network interface at a time as I disable wifi intentionally when I use ethernet.
Other apps can just detect automatically which network interface is used.
