In the Google Workspace Admin console, for the Gmail settings, it’s possible to create routing routes based on pattern matching of the envelope recipients. It would be great if it was possible to capture the envelope recipient too, so that the “Change envelope recipient” can create more dynamic rules.
For instance, we have group@wcj.se that we want to reroute to group.wcj@dans.se. Here, group can be any alphanumerical string. This is impossible to do at the moment.
