I have a user that is requesting to enter a distribution list in the request participants field in JSM or Jira and have that get all the users within that DL to add to the Request Participants field through automation. We have a really screwy way of doing it right now which is a pain and I'm trying to make it better. For example, user enters "analyticalavengers" which is a DL and our automation finds if this is entered then add all the users manually based on their ID to Request Participants and remove the ID of the DL.

This is the Edit Work item fields

Does anyone have a better idea to do this? Thanks.
