Can we mass amend recruiting content library notifications in one go

We are amending Candidate notifications from Recruiting Content Library on customer request. In those notifications we have company branding images as header & footer in the notification. We want to update all those notifications however in content library we have to do it one by one to update all the candidate notifications to amend header & footer.

Is there other possible place or way to update all notifications in one go
