Please add them! It would be very nice to have!
My usual usecase is to capture both phrases "level one" and "first level" in the same intent, and it would be extremely nice to avoid creation of my own LevelType that capture them. And then another EpisodeType to capture "episode one" and "first episode". And another SegmentType with "segment one" and "first segment". And so on.
Thank you for concideration.
