is it currently possible to import file contents into pillar?

For example I have a script stored in my-script.st and I would like to do something like

[[[source=my-script.st

]]]

or��

{import 'my-another-pillar-file.pillar'}

or something like that.

I can overcome this with some bash preprocessing, but is there some syntax, or plan for it directly in Pillar?

Thanks,

Peter
