So far things are going well, but I was setting up some group automation today and ran into something that seems will require two scheduled pieces instead of just one.

I want to have a group populated with updated membership from a CSV (just contains the sAMAccountName).  I figured I could use an Automation Policy and add two steps, one to remove all members and a second to add the memberships from the CSV.  I can't figure out how to do the second piece using an Automation Policy.  It's an easy task through normal automation, but I don't see anywhere to specify the CSV for adding members to a group.

Is the only way to do this have two tasks?  One to remove all the users from the group and then standard Automation process to add the users from the CSV?
