Support filters (queries) on the Change Feed
For some advanced scenarios and for performance reasons, support filters (queries) on the Change Feed
This is on our long term roadmap and are still evaluating this but no ETA. Will update as this changes.
Thank you for your suggestion.

I agree. With cosmos you are encouraged to put multiple document types into the same collection / partition so they can be update together in a sproc transaction. The down side to this is then you subscribe to that collections change feed and you’re probably going to get a lot of function executions for changes you are not concerned with. This impacts scale and cost making it less viable. A filter on what causes the trigger to fire would solve this.
I'm very keen to see this feature to put in as well.
got my vote!
Cosmos DB should support predicate pushdown for Change Feed so users can filter out documents they don't need.
