I put the art#'s and link to the google doc inside the production notes field in Printavo, it looks like this on a browser (cropped to not show client info). What I really like about this whole setup is that the job as it is approved by the client is the only thing everyone works off, save for having to link that press info. Also, all our press data is on our servers, not a mgmt programs so if Printavo were to go under we wouldn't have to export everything out of there which always leads to some sort of formatting headache.
We're migrating to a local server setup, OSX Server, this month so instead of link it will just be the art#'s and you'll have to search that art# form the ipad in the database and pull it up. One more step but worth it as the drop down menus in my job sheets will be usable from the tablets now (google somehow decided to not enable data validation on it's sheets on android...).
None of this is ideal, your FM database is superior since it can do things like aggregate all the screens needed in a week, etc. We do OK just typing this into a third app that we hold checklist type of data in for each job.
