Is it possible to configure wildcard in the middle of a path

[suntsu42]

The following example works, and applies to all content after /foo

  "route1": {
        "ClusterId": "cluster1",
        "AuthorizationPolicy": "customPolicy",
        "Match": {
          "Path": "/foo/{**catch-all}"
        }
      },

I now want to add a route which applies for all traffic which ends with something specific, but the middle part should be wildcard

  "route1": {
        "ClusterId": "cluster1",
        "AuthorizationPolicy": "customPolicy",
        "Match": {
          "Path": "/foo/{**wildcard}/bar"
        }
      },

In this case, the error message is: A catch-all parameter can only appear as the last segment of the route template.

Is there a way to configure a route which does apply a wildcard which is in the middle of the uri?
It my example, it should be applied to
/foo/demo/bar
/foo/xyz/bar

I think i now found the solution by using message:regex

          "Path": "/foo/{message:regex(.*)}/bar/{**catch-all}"

But transforms using the path from the regex (something like that:)
"Match": { "Path": "/foo/{message:regex(.*)}/bar/{**catch-all}" },
"Transforms": [
{ "PathPattern": "/foo/$1/bar/{**catch-all}" }
]
are not possible, as far as I know. Or is there a way to do that and I just missed the point?

Try { "PathPattern": "/foo/{message}/bar/{**catch-all}" }
