Converting PromptVersion to Templating Template: Best Practices

Hi all, is there an official, graceful way to convert between phoenix.client.types.PromptVersion and phoenix.evals.templating.Template?

phoenix.client.types.PromptVersion has a _dumps which allows me to get the raw template, but it's an internal method. Otherwise format only produce the final prompt with all variables provided. I can probably do something like this: prompt.format(variables={"text": "{text}"}) but that seems a bit hacky.
LLMEvaluator class receives a prompt_template parameter, so I need to have the raw prompt available.

Any help is greatly appreciated. Thank you!
