How to make RTW options persist.

When compiling a Simulink model with RTW (r2013a), I need to check "Code Generation > Interface > Code Interface > Generate reusable code" every time I open the model. I would like to automate my building and so I either need to have this option saved in the model, or drive it from the command-line before building.
This is the only parameter that doesn't seem to be saved in the model. Others like "System target file" save just fine and I don't need to reset them. My guess is that this is a bug in my version of Matlab (r2013a).
So my next question is: How can I over-drive this parameter from the command line? My current method of running this model is:
matlab ^
-nojvm ^
-nodisplay ^
-nodesktop ^
-r "addpath('%modelpath%'); addpath('%tlcpath%'); addpath(genpath('%scriptpath%')); rtwbuild('%modelname%'); quit;" ^
-logfile %modelname%.log
It's possible that the long -r parameter can be turned into a .m file. I think I can set this with:
cs = Simulink.ConfigSet;
cs.set_param('MultiInstanceERTCode', 'on');
If I put it in my build-script it doesn't seem to do anything (probably because my model isn't open yet). If I save it in my "Model Properties > Callbacks > PostLoadFcn" it also doesn't seem to do anything.
Another thing I've tried is:
hCs = getActiveConfigSet('b737ng_yd_solenoid')
hCs.saveAs( 'ConfiguredDataScript', '-format', 'MATLAB script', '-varname', 'config_set')
I've done this before and after swapping the "Generate reusable code" and I do see the difference in the resulting script. However running the script before opening the simulink, or running the script with the simulink open will not restore this specific flag.
I am going to just try installing a new version of MATLAB to see if this is fixed in a later release.

I solved this by simply updating the models to MATLAB 2015a, setting the "Reusable Code" flag, saving, and then compiling by simply calling "matlab -r rtwbuild(model)". No need to deal with options via command-line in MATLAB 2015a.

You can use Simulink® Preferences to specify Simulink editing environment options and default behaviors.
In the MATLAB® Command Window, enter slprivate('showprefs')
Here change the preferences in Configuration Defaults > Code Generation > Interface.
This will change the default options.

Thanks for this answer. When I use slprivate('showprefs') to enable this feature, new models I create have "Generate Re-usable code" pre-selected. That's great! However, if I open an existing SLX, the option is not selected.
I've tried selecting, saving, closing, and re-opening again and the option refuses to persist.
In addition, I have lots of users opening the models. It would be best if the solution isn't user-environment-specific and can be tied to the model which is controlled in a version control system.
