@lisama7982_5385 this would require using the Docker API, which is kind off a pain, but if you search for things like "how to tag an image with a digest usng Docker API" or something you should find it eventually
You can also use the Docker CLI by doing something like docker pull using the digest, then docker tag, then docker push.
If this is a one-time clean-up you may also wish to query the database tables, like Docker* tables will allow you to eventually find what images you need to tag. Just don't delete from the database, since that can cause a headache and it won't delete files from disk
Hope that helps :)
