Topic: adding an additional comment to Taxon Occurrence Comment using TOKey

We have a wonderful tool which allows us to add a verification comment to the determination comment field using the TOKey, it came from Cumbria (many thanks). I am wondering if anyone has something similar that would enable an additional comment to be added to the Taxon Occurrence Comment field using the TOKey and held within brackets []. Any help appreciated.
