Is there the option in Supermetrics For Google Sheets, or any other way to use Google Analytics Custom Channel Groupings instead of just the Default Channel Grouping?
thank you for contacting us. Please visit our support documentation for missing metrics / dimensions.
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.
