Get typesafe child routes list

[UltimateGG]

I often find myself making functions that for reusability sake have shorter paths.
For example if I had
/page/subpage/a
/page/subpage/b
/page/subpage/c/hello

I may have a function, component, link, etc. like this:

const changeSubPage = (subPage: string) => {
    navigate({ to: '/page/subpage/' + subPage });
}

Is there a way to get that subPage: string to be '/a' | '/b' | '/c/hello'?
You can get the link type, but that is all full paths (#429). This may be tricky because its strings vs typescript but I thought it may be possible because in routegen file it does contain the separated paths (path, and fullPath)

You could use something like this:

type Parent = '/page/subpage/'
type ParentRoute = RouteByPath<RegisteredRouter['routeTree'], Parent>
type ChildRoutes = ParentRoute['types']['children'][keyof ParentRoute['types']['children']]
type ChildPaths = ChildRoutes['path']

const changeSubPage = (subPage: ChildPaths) => {
      navigate({ to: `/page/subpage/${subPage}`});
}
