Thanks for getting in touch! Currently this is not available in Octopus, though it sounds entirely reasonable to expect it to work. I’m going to bring it up with the team to see if this sort of behavior should be implemented.
In the meantime, there are a couple of options available to you. The first would be to use our API in a step during your runbook to reference the dashboard to return the desired release and associated version. As the dashboard represents the latest successful releases to each environment for each project, this information should be exactly what you are after.
Below is a simple script I put together that you can edit and make your own to best meet your needs if you decide to go with the API.
