Is there a way to add entire roles as collaborators to an investigation rather than just one at a time?

Hi all,

I'm using ES 4.7.3 and as far as I know there is only the option to add collaborators one at a time to an investigation. This doesn't work well with our existing structure of incident response (cases are not assigned to users, but the group and users take incidents from the list of active ones).

The logistics involved in adding every user to every investigation is pretty time consuming, I'm hoping there is a basic functionality to add batches of collaborators to investigations.
