Can you build utility functions in liquid?

[CliffM]

We have a requirement which will cause us to have to conditionally format the HTML dynamically for currency values, similar to this,

Unfortunately, there are close to 100 currency points within our model that would be affected so I’d like to be able to encapsulate this to a single convert_currency_string(value, currency_code) type function. Is there a way to support this broadly available utility function concept?

Thanks in advance

Unfortunately not. Currency is one of those things that could really use with some advanced DRY patterns in LookML but we haven’t seen any improvement in that area. 

I proposed something that I think you’re referring to. Ability to create a constant that could be used in value_format_name

This one is based on a parameter but it would be great to make it based on the data itself too
