Yes, you can. You must first sign in to the Studio Content Manager to stop a single video outside your ownership territories. Once that is opened, you must click on the option showing videos. Then you have to click and select the video that you want to block. After this, open the tab on Rights Management and go to the ownership section. Once that is opened, you have to click on 'Select Specific Territories' and then choose an option. Once that is done, you have to select the box so that you can block videos that are outside your territories of ownership
