Hello Stephane,
There's no way to do that currently -- sorry. The layouts are independent for each organ, so that you can customise them according to the different ways in which one might use different styles/sizes/specifications of organs. (For example, some organs have plenty of general combinations of their own, whereas for others one might want to use Hauptwerk's Master Generals. Also, different organs have different numbers and layouts/sizes/aspect ratios of virtual console screens.)
