I've modified an IG data file to cover the Astra Militarum codex. Look here if you're a Battlescribe user and would like to try it out. Feel free to give me feedback. There's another one here that's not my work. There's also a Militarum Tempestus data file here which is not my work.
--- UPDATE ---
I've updated the file with corrections that I found after building a few lists.
--- UPDATED (AGAIN) ---
A few more corrections and some profiles added
