Configuring host or interface MTU

Problem:
When I create or edit a host there is no field to set the mtu, neither for the host nor any interface. There is a parameter host[interfaces_attributes][mtu] in the API to set it. Is that intended?

Expected outcome:
Textfield in the gui to set the MTU of an interface.
