i can cut with forks, and drink with potatoes. -Simo Paga 2017-
I'm pretty sure I've read that by design you cannot do so (e.g. to avoid someone pranking/annoying/trolling someone else, e.g. by giving them an inappropriate microbadge). But I am not certain.
In any case, I've never heard of any way to do it in the BGG user interface.
Ok, thanks for the answer.
