Ability to add parent to mutation

[Hyra]

When adding an item through a mutation it's only possible to add these native fields, besides any custom fields added to the section:

id: Int
siteId: Int
authorId: Int
title: String
enabled: Boolean
query: MutationQuery

But not other fields such as 'publish date', 'status', 'parent' or 'slug'

Is there a way to add these fields when upserting an item?

Example (trying to add field slug):

mutation {
  upsertProgramsStructureSeasonsDummy(
    title: "Example entry"
    slug: "some-custom-slug"
  ) {
    id
    slug
  }
}

In addition...
I really need to be able to mutate the structure articles, meaning I need to define which parent this article should be placed beneath.

mutation {
  upsertBlogCategory(
    title: "Example entry"
    descendantOf: 3 // This needs to work!!!
  ) {
    id
    title
    parent: { // This already works
      title
    }
  }
}

These changes will make it in to the next release, a few notes though,

1. Instead of publish date try postDate and see if that gets you what you're looking for
2. status is a read-only (computed) field based on the enabled flag and the postDate check. You can't actually set the status
3. parent will be implemented with the new parentId: attribute since that's how it is referred to internally within the Craft 3 API
4. slug will be implemented with the new slug: attribute

I forgot to add #199 in to my commit message for the parentId: attribute. Here is the code change that will go out with the next release,
