Formatting Options in Email Designer

Description -

Why is this feature important to you - Product Price in Order Confirmation / Recommendations in Email Designer

How would you like the feature to work - Flexibility for formatting/ ability to do some calculations on available personalization fields (similar to https://experienceleague.adobe.com/docs/target/using/recommendations/recommendations-design/customizing-a-template.html?lang=en#customize-a-design-using-velocity)

Current Behavior - 1. Product price (through custom resource fields) which is stored and already rounded to 2 decimal places is displayed with 12 decimal places and there is no way to fix that. 2. data-nl-* attributes and their usage is not documented. Would need the flexibility to change/ manipulate these in Email Designer source code.
