• Group "All" is equivalent to the default choice, all active nodes. This wildcard should not be used as we will likely retire it in a future version of opReports.
• Group "Each" is available for scheduled reports only, excluding 'once only' scheduled reports, and causes the generation of a separate report for each of the known groups.

separate report for each group

This feature was added to opReports in version 3.1.8.

This option causes the generation of a separate report for each of the known groups.
This option is available for scheduled reports only, excluding 'once only' scheduled reports. 

Groups must match the regular expression given for the group name AND
Nodes must match the regular expression given for the node name AND
Interface descriptions must also match a separate regular expression.

Only those interfaces are selected where all three regular expressions match.
However, for reports where interfaces are not relevant, interfaces are disregarded.

...

In the GUI this option is called "by Regular Expression for a Nodes and Interfaces Report per Group".
opreports-cli does not support this option.
The report schedules requires that you supply group_each_regexp=<regular expression> AND node_regexp=<regular expression>  AND node_intf_regexp=<regular expression> .

All three regular expressions are evaluated at report creation time.
