No way to rename enum variants

[Lynnesbian]

The TOML I want to parse looks like this:

[podcast.example]
on_error = "skip_episode"

I tried to parse it into a model with an enum, like this:

public enum OnError {
	SkipPodcast,
	SkipEpisode,
	Abort,
}

Tomlyn expects to read values as PascalCase rather than snake_case, causing an error:

Error: (45,1) : error : Exception while trying to convert System.String to type GrabCastSharp.OnError. Reason: Requested value 'skip_episode' was not found.
(45,1) : error : The property value of type System.String couldn't be converted to System.Nullable`1[GrabCastSharp.OnError] for the property GrabCastSharp.Podcast/on_error

I tried to use DataMember annotations to rename the enum variants, but it had no effect:

public enum OnError {
	[DataMember(Name = "skip_podcast")]
	SkipPodcast,
	[DataMember(Name = "skip_episode")]
	SkipEpisode,
	[DataMember(Name = "abort")]
	Abort,
}

Is there a way to achieve this?
