linked categories without creating new one


Your problem description is pretty confusing to me and I'm not entirely sure what it is you like to do (i.e. what the output should look like).

Can you generate a reprex of the problem and also provide an actual example of what the input / output should look like. A reprex consists of the minimal code and data needed to recreate the issue/question you're having. You can find instructions how to build and share one here:

Good luck,
