Hi @bklempa !
Thank you for providing such a detailed write-up!
As mentioned in Decimal Place Formatting Issue, Tulip is targeting enhancements related to this topic to provide customers more control over enforcing number formats to be delivered in a future release, with more detail to come soon.
We’d be interested in some of the use cases you mention and better understanding your perspective and need here - would you be open to a quick call with our Product Team to discuss in more detail?
