How to assing several resources to a task

Hi all,

in the Service Request window (we are on EBS 12.1.3+) I can assign resources (by selecting one by using the scheduler) - cf. below.

But how can I assign multiple resources or defined groups or teams?

We have for example the task "unload cargo" which we want to be done not only by one resource, but by two, three of four since this reduces needed time.

Any ideas how to manage this? Is this possible in Oracel Service or Field Service?

Thanks a lot for any help!

Kind regards

Oliver
