Let me clarify what I'm asking. Let's say you have a dropdown menu in the character sheet labelled 'Proficient?', with options 'Yes' or 'No'. The default is set to 'No'. If you adjust it, it changes some attribute on which other rolls rely. Using chatsetattr, I can adjust that attribute to whatever it should be if 'Yes' was selected, but on the character sheet it will still look like 'No' is selected.
