Is there an option to make poudriere install implicit ports from repo instead of building them

[Mel Pilgrim]

I only need to build a single port plus the handful of private 
meta-ports I use for role management.  It seems a terrible waste to have 
poudriere build the 500+ completely stock dependencies they pull in.  Is 
there a way to have poudriere install implicitly-added pkgs from 
pkg.freebsd.org instead of building them?
