[MM3-users] Add an extra option for "Delivery status" for users?

Hello!

We have a unique case where we have a user we want to disable for mail receiving, etc. for the reason "Disabled by IT Security Team" but I don't even know if it's possible to add a delivery status that is that custom.

I know we have "Disabled" and "Disabled by Owner" but would we be able to add/modify the list to add that option (so that list owners can mark it)?  (I say List owners because the ITSec team at a client has 'owner' status by default, without an extra group, but we want to have a dedicated dropdown selection for the ITSec team, even if we just have to duplicate "Disabled by Owner")
