Is it possible to use a value other than the Default Organizer value for Calendar Meeting Invites?

Summary: We can change the default email address used to send Learning calendar invites via: My Client Groups -> Learning -> Setup -> Configure Alerts -> Default Organizer for Calendar meeting invites page.

We have one value set here with our Learning team's email address and this is applied across our whole organisation.

Is it possible to apply different default values? eg we have several regions within our organization (Asia Pacific, North America, UK/Europe) and it would be great to be able to specify the Learning email address that applies to each region, according to the region each learner is based in.
