better way to provide negative tokens types

[bwyx]

i want my custom utils strict using only the tokens i provide..

is there a way to provide negative space tokens types without redefining all the tokens? since using dash for tokens are prohibited either 😕

const styles = createStitches({
  theme: {
    space: {
      '-1': '-0.25rem' // nope
    }
  }
})

currently i solve this by extracting space object and manually define the types like:

type Space = Stitches.ScaleValue<'space'> | `-$${keyof typeof space}`

const space = {
  1: '0.25rem',
  2: '0.5rem',
  3: '0.75rem'
}

const styles = createStitches({
  theme: {
    ..,
    space,
    ..
  },
  utils: {
    mt: (value: Space) => ({
      marginTop: value
    })
  }
})
