Dynamic request routing based on header-values

For our QA environment we need to configure a special kind of routing for the incoming (Ingress), but also for the outgoing (Egress) requests. So for outgoing requests the rule should evaluate a header value with a regex and capture a value from the header and build with that value the URL where the request should be redirected. The value in the header is dynamically changed, so the redirect URL can not be hardcoded.

For example if the outgoing requests goes to services-master.anydomain.com, but there's a header value forwarded-for-feature with the value verbu-1234 the request should be redirected services-verbu-1234.anydomain.com.

For incoming requests it's a similar condition. If the origin points to webapp-verbu-1234.anydomain.com, but the request goes to services-master.anydomain.com the regex should extract verbu-1234 from the origin domain and replace master in the URL with the extracted value.

I know, that it's possible to use a regex to match header values, but I'm not sure, if it's possible to use captured values from a match to influence the target URL, at least I couldn't find that in the documentation.
