I have a context with about 27,000 users. Most of these users have home
directories on a volume I am trying to remove, however, if I try to do a
backfill to force the home directories to migrate to the new volumes set
up for these users, so many jobs get queued up that the server abends.

In the browse object window, there doesn't seem to be any way of selecting
multiple users against which to run a backfill. It appears that the only
options are to backfill against the container or pick one user at a time.
Is this the case? If so, is there any chance of the ability to pick
multiple users in the future?
