Import objets

Icinga Web Modules Icinga Director

Hi,
I see that I can export:
datafields Export all DataField definitions
datalists Export all DataList definitions
hosttemplatechoices Export all IcingaTemplateChoiceHost definitions
importsources Export all ImportSource definitions
jobs Export all Job definitions
syncrules Export all SyncRule definitions

But only can import:

importsources Import ImportSource definitions
syncrules Import SyncRule definitions

Are there any way to import this other object?
Are there any plan to add import to this objects?

Thanks in advance and best regards,
Emilio J.
