How to extend the vertical zoom to all the opened signals?

On Adobe Audition 3.0 we could choose an option to "synchronise the cursor on woindows". It had allowed to apply the same zoom in amplitude to all the opened signals. 

With new Audition, we can still keep the same zoom in time for all the signals but we have to zoom in amplitude for each of them, which could be really long!

Is there an hidden option sowewhere to make this functionnality alive again?
