Add note on RoHS compliance to all drawings in vault

Hello everyone, I currently do not have Enterprise PDM but am considering it. We have Workgroup PDM presently and I know SolidWorks is phasing this out for their new tool. Anyway, my question is really about best practices for updating all drawings in a vault or subfolder of a vault ideally. Can a note be added automatically to all drawings to ensure RoHS compliance (just one example)? My engineers are hesitant to update the 1000 or so drawings due to the time it would take and I thought there must be a way to automate something like this. Any suggestions?
