Where is the "installation list" function ?

I recently installed a trailer hitch on my A4 B8, and I wasn't able to complete the coding with my HEX-NET + VCDS mobile.
The last step was checking the trailer in the installation list function of the gateway (19).
The problem was I didn't find this function...

I solved the problem taking a friend's PC and using VCDS...

Is there and equivalent to this missing function in VCDS mobile ?

You weren't missing it - that function is not supported with VCDS-Mobile at this time.
