paper-trail-gem

I was wondering whether the following use case can be achieved using the papertrail gem? A Wikipedia-type of application with wiki pages that logged in users can change/edit and where: Moderators can undo specific changes: I understand papertrail allows to roll back to a previous version but what I’m asking here is somewhat different. That is, the ability to undo a specific edit/change . Suppose there have been three edits/versions to a record/wiki-page. Then if you want to undo edit 2, then changes from edit 1 and 3 should still remain. But if you would roll back to the version before edit 2,

My question: Should I roll my own model versioning or use one of the versioning gems that's already out there? If I should use a gem, which one seems best for this application? Info about my app My app is a simple Checklist app. There are Checklists and Jobs, and I track user responses with Responses and Submissions. The Response tells me what the use said ("Done", with a note "We need more mops.") and the Submission tells me when that particular Checklist was filled out (because there may be many submissions and sets of responses for a given checklist). I'll show my associations below, in
