Using dynamic queryParams in Ember

I'm writing a search application that allows filtering by certain search facets passed by the API, for example:

searchFacets: [
  {
    name: "color",
    values: ["red", "green", "blue"],
  },
  {
    name: "size",
    values: ["small", "medium", "large"],
  },
  {
    name: "age",
    values: ["young", "old"],
  },
]

When the user wants to filter search results by a certain facet, the API expects a request with selectedFacets being a queryParam that is an object representing all selected facets:

selectedFacets: ["color=red", "size=medium"]

So currently, the URL for the request would look something like search?selectedFacets=["color=red", "size=medium"]&keyword=blah&someOtherParam=foo

However, I want the URL to show a deconstructed version of this selectedFacets object, while still retaining the object under the hood in the API request, so it would look something like search?color=red&size=medium&keyword=blah&someOtherParam=foo

The only problem is, I don't know the search facets (i.e. color, size, etc.) ahead of time, so I can't just specify them as queryParams in the route.

Is there a way to dynamically set queryParams programmatically, or translate a certain queryParam so it shows up this way in the URL?

Thanks!
