I can't think of any reason to go to the trouble of adding the ability to create a template to DHP as well. What is the reason?

Please report only one suggestion in each issue.

For the first suggestion, there's a plan of integrating misode's data pack generator into DHP as they share the same underlying schemas. Soon :tm:.
