Using E-Drawings to mark-up drawings

I've been asked to look into how we use e-drawings to write mfg notes on released drawings in EPDM. Currently we've been using a piece of software called Jobpack but it doesn't seem to play nice with EPDM. What we want to be able to do is to allow people in manufacturing and operations to be able to write their own notes about set-ups, problem areas with machining, ect. I think we can do this with edrawings but I'm not sure the best way to go about this. Some of the people making these notes would be machinists so I'm not sure we want to give them checkout rights with released drawings but is there a way we can get them the ability to mark things up?
