Currently there are only twos ways to add default metrics to a report:
1) For eVars, you can add only three default metrics via the admin section
2) For props or out-of-the box reports, this cannot be done via any admin section and must be done at a report level
To add default metrics on props/standard reports, or to add more than 3 evar report, you have to add to a report then set per report. This can take hours to do for a single RSID. If I've got 100-1000 RSIDs with the same settings, there is no way to set and copy default metrics.
Can this be added as a feature? Even exposing this via the API would mean significant time savings.
