Can I redirect with wildcard in Azure Static Web App?

Question

I'm trying to redirect API calls from my Static Web App to another Function App but I can't get wildcard to work.

The route matches correctly but I want the * part to be included in the redirect. This is an example from my staticwebapp.config.json

  {
        "route": "/api/client/*",
        "redirect": "https://xx.yy.net/api/client/*"
  }

I would like the request /api/client/customer/get?customerId=xx to become https://xx.yy.net/api/client/customer/get?customerId=xx.

But whatever I try it only hard routes to exactly what I put in the redirect. With functions this is possible with a proxy but I can't find a way in a Static Web App.

A bit late, but in my case it was possible to get the original Url from a header:

        if (shortUrl == "*")
        {
            var original = req.Headers
                .FirstOrDefault(h => h.Key.ToLower() == "x-ms-original-url")
                .Value.FirstOrDefault()?.ToString();
            if (string.IsNullOrWhiteSpace(original))
            {
                shortUrl = "";
            }
            else
            {
                shortUrl = original.Split("/")
                    .Where(p => !string.IsNullOrWhiteSpace(p))?
                    .LastOrDefault() ??"";
            }
        }
