Good day. Is it possible to include a field within theme designer that would display different information based on a calculation + custom variable? I'm interested in developing an achievement system (similar to ones present on some non-DNA devices) which would "reward" the user based on how much they vape and what wattage they use. If yes, then how would one go about it? Is there an existing theme or tutorial I could take a look at? Thank you very much in advance.
