BVI doesn't show up in multi context ASA

I have an ASA 5585 in transparent mode, multi-context. It seems that the option to configure a BVI in one of the traffic contexts isn't there. In other words, while I see the option to configure a bridge group interface in the admin context, no such option comes up in the traffic context.

ciscoasa/admin(config)# interface ?

configure mode commands/options:
  BVI         Bridge-Group Virtual Interface
  Management  Prefix of interface Management0/0
ciscoasa/admin(config)#

ciscoasa/admin(config)# changeto context dmz
ciscoasa/dmz(config)#
ciscoasa/dmz(config)# interface ?

configure mode commands/options:
  Port-channel  Prefix of interface Port-channel30.411, 30.412, 30.413, 30.414
ciscoasa/dmz(config)#

I thought that maybe I need to first allocate BVI interface(s) in the system context (in order to seem them in the traffic context) but that doesn't seem to be an option either.

ciscoasa/dmz(config)# ch system
ciscoasa(config)# interface ?

configure mode commands/options:
  GigabitEthernet     GigabitEthernet IEEE 802.3z
  Management          Management interface
  Port-channel        Ethernet Channel of interfaces
  Redundant           Redundant Interface
  TenGigabitEthernet  Ten GigabitEthernet
  <cr>
ciscoasa(config)#

Has anyone seen this or know what the issue is? Thanks.

I think I figured it out. It seems that when you create a context, it is created in routed mode by default. So you have to explicitly go in and change it to transparent mode. Then the BVI interface shows up of course.
