We can see who the TRs are because they have a symbol book-ending their name. I think it would be a good idea to give completionists a different symbol so everyone can see who they are and thus rewarding them for their efforts. Double and triple completionists could have different symbols.
I have no toons who are currently completionist but I am working towards it (a long-term project that I don't expect to be finished by the end of the year).
I don't know how this would work with the Epic TRs that are due next week but I'm sure something could be worked out.
