As of R2018b there is no better workflow than opening a script and using the "set_param" command to center and zoom individual subsystems.
Question
Hello, We have been trying to get a reliable and quick way to ensure all of our models and subsystems are centred on the screen and are at 100% zoom.

The following script ensures ensure all of your models and subsystems are centered on the screen and are at 100% zoom:
subSys = find_system( modelname, 'BlockType', 'SubSystem' );
for ss=1:length(subSys)
subs_h = get_param( subSys{ss}, 'handle' );
open_system( subs_h, 'tab' );
set_param( subSys{ss}, 'ZoomFactor', 'FitSystem' );
set_param( subSys{ss}, 'ZoomFactor', '100' );
close_system( subs_h, 'tab' );
end
