hey Abi C.: this isnt quite there yet as a feature, but i know other customers have asked about this. and the product team is looking into this.
also, does your team use slack? im thinking of something like a recurring reminder message sent to a slack channel where all the risk owners/contributors are located, all powered by slack's native workflow builder tool. can offer further insight if thats of interest.
Also i think this would be a great thing to flag (+ any other Risk questions you might have) as part of the upcoming Ask Me Anything session with Toni here in Slack; she is the Risk product leader at Vanta (the perfect person to ask!)
you can submit as many questions as you'd like using this workflow.
