Does anyone know if there's a quick way to change the pitch of multiple midi objects at the same time in Music Maker 2015 ?

At present if I want to change the pitch of a song I'm having to individually select an item, change the pitch and  then carry on doing this process for every midi object - which is quite time consuming.

Just wondered if there's a quicker way to do this. I've tried selecting multiple items at once and then changing the pitch but this only get's done for the initially selected item.

Thanks for any help or suggestions.
