Well, there is definitely a deeper issue at hand here, but just in case someone wants to do what I was suggesting, here's how it can be done -
Create a plugin (you can just type it in after clicking "New Plugin" on the elements tab), and make the body of it contain the line:
$resource->set('syncsite','0');
And then use the "System Events" tab in the plugin editor to set it to be called on "OnDocFormRender".
But as Saschame is getting at, it probably won't solve your problem, ultimately.
