This is very simple but extremely helpful for those of us that watch multiple streams for different games or campaigns.

Here's an example of how it would work. A user would be able to gain completion towards drops for streams as long as they are of different events. In other words, if I am watching for RainbowSixSeige streams with drops enabled, I could also open another tab for Rocket league and gain progression towards both drop campaigns.

Even better/intuitive is if it is per campaign so I could watch 2 different (example) Rocket League events such as RLCS and CRL and still gain progress towards each respectively.

This would allow the process to be mroe streamlined and convenient.
