Hi There,
If you have the files and it is not there you need to add yourself.
It should not take logo, you can change the increase the canvas(alt+ctrl+c) height in 40px on and select all layers and pulled them 20 pixels down, what can be done by clicking : ctrl+T than hold shift and and press the down arrow 2 times.
Anyway I will pass it on your suggestion for the responsible sector.
Hope that helps
Joao
