Currently setting Manage Conflicting Processes at the top level automatically applies to all products in the catalogue and you can opt products out of that option.
Alternatively if you only want Manage Conflicting Processes for a handful of products you have to set them per product and manually configure it each time.
It would save customers time if they could set Manage Conflicting Processes options globally and then assign them to individual applications using right click instead of them applying to all products.
