MVC Route With Array Of Homogeneous Parameters?

I trying to create routes for a resource with an array of homogeneous parameters.

URL would look like this:

products/category/{categoryId1}/{categoryId2}/.../brand/{brandID1}/{brandID2}/...

And would like an action method would look like this:

public ActionResult GetProducts(IList categoryID, ILIsts brandID)
{...}

where category and brand are independent filters.

I found a solution for similiar task:

[URL]

And wonder if there is no more beautiful solution that allow to use this prototype public ActionResult GetProducts(IList categoryID)

instead of public ActionResult myAction(string url)for action method to avoid splitting the string and casting?
