Need terminus to allow plugin updates for multiple sites with one command

[FRNetwork]

Expected behavior

The current command (terminus wp my-site.dev -- plugin update --all) will update a single site.
We need a command that allows us to push out plugin updates (and other types of updates really) to multiple sites without running the command multiple times.
A sort of
terminus wp my-sites.alias -- plugin update --all
command where I have all of my sites from the site:list command stored in an alias file perhaps?
Not sure of the best mechanics for that, but the command should allow me to push updates to all of my pantheon sites.

I appreciate any comments or ideas.

I am quickly getting 30+ sites in place and I have another 100+ I manage, and I won't be bringing them to Pantheon if I don't have a unified way to manage updates. I currently use the ManageWP Orion tool to manage my non-pantheon sites and I can push an update to all of them with one command, however Orion currently doesn't play well with Pantheon sites.

There is a plugin available for this at the moment https://medium.com/@Pixo/automating-plugin-module-updates-on-pantheon-bfc6e13dac39#.fcscnndnm

Yep, saw that it came out today via the Pantheon blog, makes me very happy.
