This feature has been very helpful. However, wondering if you're planning on adding the ability to just select exclusions only, and if there could be a way to bulk exclude from all widgets or a full dashboard report (so that we don't have to apply at each widget).

For example, we need to exclude visits from China. In order to do so, we must "select all" then uncheck China. What this does is open up the potential for new countries that pop up in the future not being included (because they weren't checked, as they didn't exist at the time). Is this something you plan on working in?

Yes, this is needed! We get a lot of spam from other countries that skew the data. This would be super helpful if you could apply the country feature to the whole dashboard like on Power BI

This is also important for those who have integration of firebase, since Google don't allow more then one property to be connected to Firebase, companies that serve multiple countries with one app are forced to use Audience/country filtering.
