The fragments currently only has 3 keys: - `name` - `check` - `showcontent` However, the format of several details of the fragment is controlled by some top-level keys. - `issue_format` - `all_bullets` - possibly more Would `towncrier` accept a PR where (at least the above two) are allowed in the fragments, but fallback to the global values? My main motivation is that separate fragments can require special formatting in terms of issues.
