Is there an option for this? I only see brand, category and product types?
all the available metrics from AdWords API should also be in Supermetrics connector. Please visit our support documentation for missing metrics / dimensions to find instructions on how to see if it has come available.
If you manage to find the missing metric or dimension, please post a link to that site in to this ticket. We'll let our development team know of it and they will contact you once it's added to Supermetrics. Please note that fitting the missing metric/dimension to data source connector may take some time. We appreciate your help with this.
