As soon as you create and save a new feed via Analytics UI, it saves the column template with some random name. It would be hard to find what the name it has been set to. So you can connect with clientcare team with an old Feed ID whose template you would like to use. We can check the name of the column template from backend and share with you. Then you can use the same with other feeds.
One option is to reach out to Client Care and ask them to setup a feed from the backend while creating a column template with those columns. Once that is done, that will be reusable in the Analytics UI, going forward.
