I have a master production template that I use for every single beat that I produce, however, I have had to update this template numerous times but the other sessions don't get updates, so for example, if I added another bus or FX channel, I'd have to go through each template individually to update it.
Studio one should allow you to create a master template so that once you make a change, it automatically reflects on your other sessions, or gives you the choice to select which of your sessions that are using the same template get updated.
