Workaround:

Follow below mentioned steps to specify GV.
1) Navigate to Advanced folder --> Sessions --> Session for which the multithreading parameter is to be specified.
2) Click Resources --> Edit Extended Properties
3) Go to extendedProperties --> dispatcherCount, double click and edit the property value by giving the global value (say '%%DefaultRVSessionThreadCount%%'). The same value will be reflected in the Multithreading Tab.
