How can several developer accounts work as a group?

We are a group of developers who work on a bunch of different iOS applications. We are not an organization, rather, a lab in an university. All of us have our individual memberships, but we want to publish all the apps under one account, to maintain uniformity. Currently we have a lab developer account, which is shared with everyone. This is not the ideal or a very secure workflow.

Is there any way to create a group where anyone part of the group can submit to the app store under the same name?
