Best practice to create users - Hybrid scenario

I would like to know what is the best practice for creating new users in a Hybrid scenario with all mailboxes hosted and no mailboxes on-premise.

Currently when creating a new user we go to our local EMC and create a 'New Remote Mailbox'.  This creates the mailbox in Office365 and the local user account in one wizard.

After the new user is created we have to manually add the user to the correct distribution groups, and security groups.

We would like a way to create new users using a template which already has the correct distribution groups and security groups.  This is how we did it prior to setting up the Hyrbrid scenario.

Is this possible?  Can we create a user from a template and have the mailbox created in Office365 at the same time?  We do not wish to create the mailbox locally then migrate it.
