For developers! Fast Internet disconnection for all programs in the sandbox

Is it possible in the next version of the sandbox to introduce the option of quickly disconnecting all programs running in the sandbox from the Internet? So that you can disconnect all programs from access to the Internet by pressing "combining hot keys" or by a separate menu item?
Now this is done in the settings for each sandbox separately and is not very convenient! And if you need to immediately isolate all running programs - this can not be done.
