Adding/ editing service contacts quickly

[willguv]

We've talked about allowing the import of spreadsheets so content teams can start using Service contacts quickly. But I'd like us to explore other ways to do this, and also make it easier to make bulk changes on an ongoing basis.

Digital teams need to be able to:

• have pages managed by a group as well as an individual. Is that as simple as changing the service contact entity to accept multiple Drupal accounts and email addresses, and giving this new contact a name?
• add contacts to a group of pages at once rather than just one at a time? Could we add/ remove a url path (like we do with the contact by path module) and all the affected pages update automatically?
• reassign pages to a new contact if a colleague leaves the organisation. Rather than complicated UI to reassign, could it be possible to change email addresses/ names on contacts and all affected pages update automatically?
