Append Entries to a Custom List Version

Append entries to the latest minor version of a major version <b>in place</b>, without creating a new version. The entries are added to the existing version and the version string is unchanged. This differs from <code>POST /custom-lists/{customListToken}/versions</code> with an <code>added</code> body, which creates a new minor version. Appends always target the latest minor version of the specified major version.
