Dynamic Data Formulas / Formatter Functions

It would be great if there was a way to apply custom formatting logic to dynamic data in Replo - for example, if you wanted to take a price and divide it by the value of a metafield to show "per-unit" price. This would also be awesome to enable custom Javascript-based formatting, like text components that show the current date + X number of days, for things like shipping estimators (currently, this must be done with Custom HTML components)
