Supermetrics Uploader does a great job of uploading the most common data from Facebook Ads to Analytics, but is there a way to include custom metrics or dimensions in the uploads?
For example, Facebook tracks many action types as clicks but the click data gets uploaded to Analytics without any way to differentiate by action type unless we can add a custom dimension like "action type." If you are running Lead Ads in Facebook, for instance, you cannot tell how many clicks are actually leads vs link clicks vs comments, likes, etc.
After discussion with Ad Analytics about this matter, we have forwarded improvement ideas to our development department. Thanks for the great suggestions Ad Analytics!
