Hi there,We'd like to group the deliveries of our recurring automated
emails, so that reporting is streamlined. We'd like to execute this by
rather than having a seperate 'DM' number for each delivery, we'd like
each type of delivery to have a pre-fix before the DM number.Bizarrely,
one of our deliveries has this pre-fix configured (No idea who did this,
or how this was done). I'd like to add it to the rest, but i cannot see
any difference in the set-up of each delivery or how to configure this
...
