I'd much like to ask again @AnnikaTjuka about this as well. I am not against it. If you make a PR @bgo-eiu, we'd kindly ask you to tell us your name so we can acknowledge your work in our next release (we store people helping us here and would update the list accordingly).

I agree this concept could be added.
