Can you add a "Disable screenshare" (local) in dm groups? ^^

Is it possible to add a little cute button in the settings to disable other's screen sharing to prevent lagging for people with bad internet?
For example: dm group of 10 people, I need to stream to let see something for 7 people but the other 3 don't want me to stream because it would cause them lag...
It would be very nice to add a feature to locally disable other streaming to prevent this.
