Google Ad Manager is very verbose, often landing millions of MAR that goes unused.

Simply being able to apply the filter which is available, I guess similar to how this works with Google Analytics reports, would allow teams to make use of Google Ad Manager more accurately.

This is important as we have customers who are incurring millions of MAR more than would be required if they could use the filters they have in their existing reporting. This actually makes the proposition of using Fivetran for Google Ad Manager reports less appealing, as the cost to get the data in is significantly higher and then requires filtering downstream adding additional cost.
